Subject: Comments for Messaging Service Specification

 

The attached HTML is a composite of all comments received as of 8/22/2000 (Yes, Marty your comments are in the list).  I had planned to arrange the list so that those typographical and grammer errors were up from.  The problem was that the review process then became very disjointed because you were forced to jump all ove the document.  I have instead arranged the comments in order of their line reference number.  Those comments that are not directed to  a single set of reference lines are at the end of the list. Notice that there are a total of 161 comments.  It is going to be a challenge to complete this task in the time allocated during the conferenc call. Look forward to the discussion on Thursday.  I have also attached the Excel spreadsheet for those who would rather have that format.

Item No. Submitter Reference Comment Status
1 David Burdett Email dated 8/21  Line 14 Arrange authors in alphabetic order  
2 David Burdett Email dated 8/21  Line 12/16 Add angle brackets  
3 David Burdett Email dated 8/21          Line 29' Add a footnote to the page after "addressed" that states "The current specification is a working draft. Some of the requirements are note yet supported". If we don't then some people might think that we are addressing everything in this version.  
4 David Burdett Email dated 8/21          Line 99' change "encapsulate ebXML" to "encapsulate (package) ebXML" as otherwise need to define what is meant by package on lines 136/7  
5 David Burdett Email dated 8/21  Line 99-100 replace "ebXML message headers and payloads" by "ebXML payloads" as the message header is covered by this spec  
6 Marty Sachs email dated 8/20      Line 100-101 delete 'ebXML message headers' since the headers are part of the structure specified in this document  
7 Ian Jones email dated 8/17     Line 102 remove the sentence starting "The main goal…" it is repeated.  
8 Marty Sachs email dated 8/20     Line 103 Agnostic' means speptical about the existence of God.  The religious meaning is the onlyh definition in Webster's Third International Dictionary.  I know that 'agnostic' is starting to be used as 'neutral' or something similar.  Please see that the glossary contains a definition of 'agnostic' appropriate to its use here.  
9 Gordon van Huizen email dated 8/21     Line 105 Add something like the following, since the spec will be have scope beyond the original envelope and header specifications: "This specification also discusses messaging service behavior that the recommended message structure is intended to support.". We need to make it clear that there are normative semantics behind the message structure, and that this document discussed them.
 
10 Ian Jones email dated 8/17     Line 106 reverse the order of the first 2 sentences  
11 Ian Jones email dated 8/17     Line 109 This may be incorrect when document is reformatted  
12 David Burdett Email dated 8/21          Line 111' Remove Service Interface or at least make it optional as Service Interface may be in a separate spec  
13 Ian Jones email dated 8/17     Line 122 Entire section will need revision if document is reformatted  
14 Gordon van Huizen email dated 8/21     Line 124-127 The list here needs to be expanded to include the itemsin the note on lines 111-112.  
15 David Burdett Email dated 8/21  Line 132-133 Fix indentation          
16 David Burdett Email dated 8/21  Line 139 text missing. Replace by copying text from lines 360-370  
17 Ian Jones email dated 8/17     Line 140 remove lines 140 and 141  
18 David Burdett Email dated 8/21          Line 143-144, 147-148 suggests that XML can be case-insensitive which it can't. Also L147, suggests that this applies to the whole spec when it only applies to packaging. Suggest moving these two comments to the start of section 2 after l 149  
19 David Burdett Email dated 8/21  Line 148 Add another bullet point to explain use of italics, e.g. Message Manifest is in italics on Line 284  
20 Henry Lowe Email dated 8/21 Line 153 as there is no other ebXML enveloping than MIME, change the "for example MIME ..." to "i.e., MIME ...".  
21 David Burdett Email dated 8/21          Line 153' Change "for example" to "specifically" as we only allow MIME  
22 David Burdett Email dated 8/21  Line 156 Container MUST -> Container that MUST"  
23 Henry Lowe Email dated 8/21 Fig in 2.1 put a reference on it such as Figure 2-1.  
24 Gordon van Huizen email dated 8/21     Line 180-189 Some degree of mapping to transport envelopes must be addressed in the spec, at least in the form of a recommendation, for interoperability.  
25 Marty Sachs email dated 8/20     Line 184-185 I don't understand what the 'standard transport level envelopes are.'  If this refers to the standard headers defined by HTTP, FTP, SMTP, etc., have all transport envelopes places to put the identity of a specific ebXML handler?  
26 Marty Sachs email dated 8/20     Line 187 Please explain 'such structures' and when the transport envelope is required.  Ifthe transport envelope is really the HTTP, SMTP, FTP, etc. header, then it is always required. This sentence seems to imply that the transport envelope is in fact something else.  What is it?  
27 Marty Sachs email dated 8/20     Line 188-189 A transport envelope is not needed for FTP.'  FTP must have some kind of headers so again, there is an implication that the transport envelope is something else.  Is 'transport envelope' supposed to be 'Message envelope'?  But if so, why is it not needed for FTP?  
28 David Burdett Email dated 8/21  Line 189' We need to specify exactly how to specify the data communication (aka transport) envelopes for specific protocols  
29 David Burdett Email dated 8/21  Linre 190-191 Change "Message Envelope" to "ebXML Message Envelope" to make consistent with diagram on page 7  
30 David Burdett Email dated 8/21  Line 193   Change "headers" -> "headers that conform to [RFC 2045]" to mandate conformance to the standard  
31 Ian Jones email dated 8/17     Line 194 reverse line 194 and 195 to match the following text  
32 David Burdett Email dated 8/21  Line 197-198' Change first sentence to "ContentType SHALL be set to 'multipart/related' on all ebXML Message Envelopes."  
33 Ian Jones email dated 8/17     Line 198 replace 'X' with Appendix D  
34 Dick Brooks email dated 8/14      Line 198 replace 'multi-part' with 'multipart'  
35 Henry Lowe Email dated 8/21 Line 199-201 199 says there are four attirbutes, but only two are listed, i.e., type and boundary (items 1 and 4  2 and 3 are missing).  
36 David Burdett Email dated 8/21          Line 199-201' Only two attributes are defined. Not sure if this is a typo or an omission  
37 Dick Brooks email dated 8/14               Line 200      replace 'four' with 'two'  
38 David Burdett Email dated 8/21  Line 201 Add an example of a Content-Type attribute  
39 Dick Brooks email dated 8/14      Line 202 replace '4' with '2'  
40 Henry Lowe Email dated 8/21 Line 204-205 If there is only one valid value, the text "is an example usage of the" should be changed to "line must be included for".  
41 David Burdett Email dated 8/21  Line 206 Limit example to just the "type= ..."  
42 Marty Sachs email dated 8/20     Line 210-211 This specification should sprcify a boundary string that cannot occur in the content areas of a body part.  If there is not sucah a unique string, then this specification should have some discussion (informative?) of how to select an appropriate string for a given message.  
43 David Burdett Email dated 8/21  Line 212 Limit example to just "boundary= ..."  
44 Dick Brooks email dated 8/14      Line 213 remove 'version=0.1' from the example  
45 David Burdett Email dated 8/21  Line 214 Move section 2.3.2 on Content-Length to before section 2.3.1 to make consistent with the list on lines 194/5  
46 Henry Lowe Email dated 8/21 Line 220  application/vnd.eb+xml  should be changed to "application/vnd.eb+xml", i.e., remove the spaces after and before the ".  
47 Dick Brooks email dated 8/14      Line 221 insert a ':' before 'boundary'  
48 Dick Brooks email dated 8/14      Line 221 remove the spaces before and after 'application/vnd.eb+xml'  
49 Henry Lowe Email dated 8/21 Line224-225 Can there be more than one header?  If no, the text "There MUST be one ebXML header ..." should be chnaged to read "There MUST be one and only one ebXML header ...".  
50 David Burdett Email dated 8/21  Line 225-227' Following on from General Comment 2 above, change last sentence to read "The ebXMl Heder Envelope container consists of an ebXML Header Envelope and an ebXML Header Document"  
51 Dick Brooks email dated 8/14      Section 2.4 add the following to sectrion 2.4:  'The header body part MUST occur as the first (a.k.a. root) body part in an ebXML message.  
52 David Burdett Email dated 8/21  Line 228 Change to "The ebXML Header Envelope conforms to [RFC2045] amd consists of three MIME headers:"  
53 David Burdett Email dated 8/21  Line 238 elete second sentence of this para as it is covered by change to L228 above  
54 Henry Lowe Email dated 8/21 Line 241-244 Is this value the same as the value in section 2.3.2?  It sounds like it is.  If it is, so state.  
55 Dick Brooks email dated 8/14      Lines 243. 244 In section 2.4.2. Replaced lines which read, 'The Content-Length header is a decimal value used to identify the total number of OTCTST contained in the constituent message body parts, includeing body part boundaries. Emple:' with 'The Content-Length header is a decimal value used to identify the total number of OCTETS contained in the ebXML header document (excluding body part boundaries). Example:'  
56 David Burdett Email dated 8/21  line 248 It wasn't clear to me what was being referred to by the "encoded" attribute. It needs to be made specific  
57 David Burdett Email dated 8/21  Line 249 I think "message structures" is ambiguous. Suggest changing sentence to "version - a value indicating the version of the ebXML Transport, Routing and Packaging Messaging Specification that the structure of the message conforms to"  
58 David Burdett Email dated 8/21  Line 251-253 Guidance or rules need to be specified on when the version (or versionless) alternatives should beused  
59 Henry Lowe Email dated 8/21 Line 253 while the version of this document is 0.1, the final released document will be 1.0.  Change ""0.1"" to ""1.0"".  
60 Dick Brooks email dated 8/14      Line 254 replace "0.1' with '1.0'  
61 Henry Lowe Email dated 8/21 Line 256 Is ISO 8895-1 identical to UTF-8?  If so, perhaps this should be noted.  
62 Dick Brooks email dated 8/14      Line 256 replace 'iso-8859-1' with 'UTF-8'  
63 Dick Brooks email dated 8/14      Line 259 remove the spaces between 'charset' and '=' and 'UTF-8'  
64 David Burdett Email dated 8/21  Line 259 Optional Support for Signed Header. This whole section strikes me as very woolly and therefore likely to be interpreted differently by implementers. I suggest that we remove this and also the reference to digital signing on L233, pending development of the security spec.  
65 Henry Lowe Email dated 8/21 Line 259-268 Do we want to say anything about multi-hop transmission of messages?  For example "NOTE: In the case of multi-hop transmission (e.g.,bridging), it will be necessary to de-crypt or re-sign header documents at intermediate forwarding nodes."  
66 David Burdett Email dated 8/21  Line 270 Change "envelope" -> "Container"  
67 Ian Jones email dated 8/17     Line 281 replace 'X' with Appendix B  
68 Marty Sachs email dated 8/20     Line 283 Replace 'transport-specific' by 'message-service-specific'  Please examine the document for any remaining instance of 'transport' which really refer to the messaging service.  
69 David Burdett Email dated 8/21  Line 283-289 It is not clear, how it is decided what entries go in the Manifest. I suggest that we replace the second sentence to the end of the paragraph with ... "The ebXML Header Document contains a Message Manifest that identifies the parts of the ebXML Header Document that are present as well as the payload information that is present. See section xxx Message Manifest, for rules on what should exist. If the Message Manifest indicates that a Payload Container is present, then it will consist of an ebXML Payload Envelope and a content portion.  
70 David Burdett Email dated 8/21  Line 284  "is/are" -> "are"  
71 Ian Jones email dated 8/17     Line 287 change 'Payload Container wil not be present' to 'Payload Container SHALL not be present'  
72 David Burdett Email dated 8/21  Line 290 Change to "The ebXML Payload Envelope conforms to [RFC2045] and consists of three MIME headers:  
73 David Burdett Email dated 8/21  Line 295 Change both "payloads" to "containers".  
74 David Burdett Email dated 8/21  Line 299 Delete "MIME header  identifies this instance of an ebXML"  
75 Henry Lowe Email dated 8/21 Line 299-300 some words are missing, but it's not clear what  please fix.  
76 Marty Sachs email dated 8/20     Line 300 I believe that the words, 'identifies the instance of an ebXML' should be deleted.  
77 David Burdett Email dated 8/21  Line 300-301 Remove second sentence as covered by change to L290  
78 Dick Brooks email dated 8/14      Lines 300/301 replace "The Content-ID MIME header identifies this instance of an ebXML is used to uniquely identify an instance of an ebXML message payload body part." with  "The  Content-ID MIME header is used to uniqely identify an instance of an ebXML message payload body part."  
79 Henry Lowe Email dated 8/21 Line 303 in the example, is "ebxmlpayload" required?  If not, how do you know that this part contains a payload?  There is no attribute saying this is a payload.  
80 Dick Brooks email dated 8/14     Line 311 replace 'header' with ''payload'  
81 Ian Jones email dated 8/17     Line 312 entire section only discusses digital signature not encryption, it is a direct copy of section 2.4.4 at line 259  
82 Dick Brooks email dated 8/14      Line 313 replace 'application/vnd.eb+xml' with 'application/xml'  
83 David Burdett Email dated 8/21  Line 312-321 See comments on Optional Support for Signed Header above.  
84 Dick Brooks email dated 8/14      Section 2.5.4 need to specify that encryption is also allowed.  
85 Dick Brooks email dated 8/14      Section 2.5.4. should specify that implementers SHOULD indicate the character set used within the payload when the content-type permits the inclusion of the 'charset' parameter.  
86 David Burdett Email dated 8/21  Line 323 Change "ebXML Payload envelope" to ebXML Payload Container"  
87 Ian Jones email dated 8/17     Line 333 replace 'X' with 'Appendix B'  
88 Henry Lowe Email dated 8/21 Line 334-355 Is the Message digest some sort of check sum such as a CRC?  If so, where does it go in the message?  
89 David Burdett Email dated 8/21  Line 334  Message Digest. I think that we should make this stricter to improve interoperability. How about ... >>>Parties may create a "Message Digest" over a "Domain of Computation" to ensure the integrity of data exchanged using messages that conform to this specification. The Domain of Computation begins with the first "-" octet of the first boundary following the ebXML Message Envelope. The Domain of Computation ends with the last "-" of the final boundary of an ebXML message.  All octets between and including these begin and end points are Domain of Calculation. A Message Digest is calculated by applying a [SHA1] or [MD5] hash over the domain of computation and storing the result in xxx.<<< What isn't clear to me is how the digest should be recorded in an interoperable way. It can't go in the  
90 Ian Jones email dated 8/17     Line 341 should the definition of '-' be the full ASCII.  I have not checked the spec, I know this is very picky but we must be exacly to ensure interoperability  
91 Marty Sachs email dated 8/20     Line 344 I believe some words are missing at the end of this line.  I cannot find anything in this document indicating where the message digest goes.  
92 Ian Jones email dated 8/17     Line 348 change 'points' to 'octets'.  
93 Dick Brooks email dated 8/14      Lines 351, 352 in example, replace lines with "Content-Type: multipart/related; type="application/vnd.eb+xml"; boundary="8760"  
94 Henry Lowe Email dated 8/21 Line 356 Section headers, such "3 Message Header" should match the boxes in figure 2-1 in section 2.1.  For example, this section should be "3 ebXML Header Document".  Make it much easier to read the document.  
95 David Burdett Email dated 8/21  Line 356 Change "Message Header" -> "ebXML Header Document" to conform to the diagram on page 7  
96 David Burdett Email dated 8/21  Line 357 Change "ebXML Header" -> "ebXML Header Document"  
97 David Burdett Email dated 8/21  Line 358 Change "each header" -> "each principal header"  
98 David Burdett Email dated 8/21  Line 364 Remove line  
99 David Burdett Email dated 8/21  Line 366 to he -> "to the"  
100 David Burdett Email dated 8/21  Line 369-370 Delete last sentence as the reason for this statement (routing headers?) is not explained. If we include it we need to specify the circumstances or reasons why information might be added  
101 Henry Lowe Email dated 8/21 Line 372-373 The first sentence isn't entirely clear.  
102 Dick Brooks email dated 8/14      line 370 replace 'he' with 'the'  
103 Marty Sachs email dated 8/20     Line 373 The word 'MAY' on this line is snot being used in the RFC2119 sense.  Removethe capitalizaiton.  
104 Marty Sachs email dated 8/20     Line 374 Please provide 'To' and 'From' subelements for TPAId.  Each trading partner should be able to select its own value of TPAId in order to use it as a local rapid locator.  
105 Marty Sachs email dated 8/20     Line 374 Please add text explaining the meaning of the context attribute in TPAId  
106 Marty Sachs email dated 8/20     Line 376 ConversationId: Please add text explaining the meaning of the context attribute on ConversationId.  SEE EMAIL  
107 Marty Sachs email dated 8/20     Line 378 Please state that the valaue of the ServiceInterface tage is stated in the TPA.  
108 Marty Sachs email dated 8/20     line 381 Plese state that the action name is defined in the TPA.  
109 David Burdett Email dated 8/21  Line 382 Change "transport-specific" -> "messaging service-specific"  
110 Ian Jones email dated 8/17     Line 383 section referred to has been removed - remove entire sentence statring, "This is described in more…"  
111 David Burdett Email dated 8/21  Line 383 Reference to Section 4 is incorrect. Section 4 is now Security Considerations.  
112 David Burdett Email dated 8/21  Line 385-386  We don't define what we mean by an application-generate message. Suggest changing definition to "Normal - the ebXML Payload Container contains data that has been provided to the ebXML Messaging Service by the software that called it. For example a business document such as a Purchase Order"  
113 David Burdett Email dated 8/21  Line 387 a -> "an"  
114 Gordon van Huizen email dated 8/21     Line 387-388 In San Jose we discussed rolling Acknowledgment and Error message types (which are both messaging-service specific) into a generic "System" message type, as the primary intent of these types is to indicate whether the payload should be processed by the application or by the messaging service. Employing the generic System type also has other benefits:  (1) It allows for additional messaging-service specific messages beyond acknowledgment and error (such as start of frame, eartbeat, etc.); (2) There is no need for application programmers to be aware ofsystem-level messages and their types or subtypes. Enumerating them may prove confusing to application developers. I also have a concern about the use of the term "messaging-service specific". Does this mean that the essages are specific to (a) a particular messaging service implementation or (b) ebXML messaging services in general? If (a), they shouldn't be enumerated in the spec at all but my hair-trigger interoperability exception gets thrown. Either way, the term could be more clear.  
115 David Burdett Email dated 8/21  Line 390 Change definition to "Manifest - lists and identifies the content of the ebXML Header Document and the ebXML Payload Container" - for rationale see reference to line 407+ below.  
116 Ian Jones email dated 8/17     Line 391 More than routing information is held in the header suggest changing description to something like 'Header-information for processing the entire payload such as routing,…'  
117 David Burdett Email dated 8/21  Line391 Header isn't just routing information. Suggest changing to conform to definition on L368-9.  
118 David Burdett Email dated 8/21  Line 405 Change "Payload document(s)" -> "ebXML Header Document principal elements and ebXML Payload Container contents"  
119 David Burdett Email dated 8/21  Line 406 Change "document" -> "data or information"  
120 David Burdett Email dated 8/21  Line 407 Add section on guidelines for use ...  >>>Document Reference elements MUST created for each principal header element that is not a Manifest or a Header element. It is RECOMMENDED that Document Reference elements are created for each top-level MIME part contained within the ebXML Payload Container. It is an implementation decision of the application or process that is using the ebXML Messaging Service to specify which parte of the ebXML Payload Container are referenced by the Message Manifest".<<<  The rational for this is that knowledge of the existence of, for example, digital signatures, routing headers, etc in the ebXML Header Document is something that the ebXML Messaging Service could usefully discover from the Manifest. Specifying guidelines on what should be referenced in the ebXML Payload Containers should help provide some consistency of use.  
121 David Burdett Email dated 8/21  Line 411 Following on from a discussion on email ... i) Change "DocumentLabel" to "DocumentDescription" ii) Add new element "DocumentPurpose" that has a definition of ... >>>"A code that enables the purpose of the referenced document to be determined without retreiving it. Some values for Document Purpose are reserved by the ebXML Messaging Service. These begin with "ebXMLHeader:" and are followed by the name of the principal header element that is present."  
122 David Burdett Email dated 8/21  Line432 TPAInfo - just a place holder that I think changes are required here, that will arise out of work in the TP group that we haven't yet done.  
123 David Burdett Email dated 8/21  Line 449 Need to update definition of PartyId to reflect conclusion (?) of the discussion on the list on PartyId - suggest we add a comment that this is under review.  
124 Henry Lowe Email dated 8/21 Line 449-467 Two comments on these lines: 1. PartyId is not defined completely and, more importantly, the parameter "context" is not defined except in what can be derived from the example. It would seem from the example, that the address 12345 is a valid address for an underlying transport which recognizes and uses DUNS numbers to message delivery.  If this is the case, then the "context" parameter would seem to reflect the mapping onto the underlying transport and a message to be sent over a CORBA transport, you would have, for example <To> <PartyId context="corbalocURL">555xyz.com/Prod/TradingService</PartyId> </To>  
125 Marty Sachs email dated 8/20     Line 458-460 More discussion of the conterxt attribute in needed.  At a minimum, the following sentence should be added following the sentence ending on line 459:   The context attribute identifies the set of identifiers from which the value of PartyID is derived.  It may either identify a standard set of identifiers such as DUNS numbers or may be a keyword which identifies non-standard identifiers agreed to by the partners who are exchanging ebXML messages.  
126 Ian Jones email dated 8/17     Line 469 Is TPAInfo mandatory?  
127 Ian Jones email dated 8/17     Line 488 Where did 'context' come from in the example, it is not described anywhere?  
128 Ian Jones Teleconference 8/17  Line 495 need proposal to address 'Not Applicable' , 'None' or validation thru DTD  
129 David Burdett Email dated 8/21  Line494 Delete "uniquely". Message Data doesn't uniquely identify a message, Message Id does.  
130 Ian Jones email dated 8/17        Line475 definition needs to be corrected  
131 Marty Sachs email dated 8/20     497 MessageId:  Please add a discussion of the attribute called for in the DTD and add the attribute to the example.  
132 Marty Sachs email dated 8/20     Line 501 RefToMessageId:  Please add a discussion of the attribute called for in the DTD and add the attribute to the example. UUID is a default value of the attribute, not the message ID.  
133 David Burdett Email dated 8/21  Line 502 Change 'Not Applicable'" to ' "NotApplicable" (case-sensitive) '  
134 Ian Jones email dated 8/17     Line 502 Why is RefToMessageId mandatory?  No obvious rational, is NotApplicable' the correct setting? Is 'None' closer?  
135 Marty Sachs email dated 8/20     Line 508-510 Please use different message ids in these example forMessageId and RefToMessageID  
136 Ian Jones email dated 8/17     Line 512 Why is 'ReliableMessagingInfo' mandatory? Is 'Unspecified' the correct work?  
137 David Burdett Email dated 8/21  Line 512 See recent email suggesting new value of "Delivery Semantics" of "CommunicationProtocol"  
138 Marty Sachs email dated 8/20     Line 516 Please delete the word "subordinate".  An attribute is part of the tag.  
139 Marty Sachs email dated 8/20     Line 517 Please remove the capitalization from "MAY".  It is not being used here in the RFC2119 sense.  Please give an example of this tag.  
140 Gordon van Huizen email dated 8/21     Line 517 <AsbestosSuitOn> A number of references in other ebXML documents indicate that the purpose of reliable messaging is for guaranteed delivery ("OnceAndOnlyOnce" semantics, which is even called out specifically in some cases). It's fair to say that this is how ebXML reliable messaging is being marketed, and a reasonable expectation to many. Why, then, do we pull back here to "AtMostOnce"? Since we fully anticipate that ebXML implementations can ride atop reliable messaging infrastructures such as MQSeries and JMS implementations, why are we reluctant to provide a value of OnceAndOnlyOnce within the enumeration for the DeliverySemantics attribute? Presumably the ability to support guaranteed delivery is negotiated at the TPA level. If a given provider doesn't support guaranteed delivery, fine. But let's at least provide a value in the message header for it.  If we are dead serious about NOT supporting OnceAndOnlyOnce in ebXML, we need to ensure that other ebXML documents make it clear that it is not supported so that expectations are appropriately calibrated. My opinion, though, is that we should support OnceAndOnlyOnce for providers that are willing to offer it.  A further issue is that AtMostOnce should not imply reliability, although in our specs it does. The literal role of AtMostOnce is limited to dup elimination. The processing and performance impact for what we currently specify above and beyond dup elimination is significant. If the intention is to provide additional semantics beyond AtMostOnce ("I don't guarantee that a message will arrive safely, but I will make my best effort to be reliable by providing persistence for all reliable messages at both sides of the link and I can tell you whether a message did or did not make it to the receiving message service persistence store"), there should at least be a way to specify whether or not a given message requires this level of reliability. Simply indicating "AtMostOnce" or "Unspecified" does not offer this distinction.  If we continue to NOT support the notion of guaranteed messages (OnceAndOnlyOnce), my recommendation would be to completely decouple "persistent" messages from "at most once" messages--a decoupling for which there is some precedence. If others feel that we should not decouple these semantics for some reason, we need to find an alternative to calling our reliable semantics "AtMostOnce". </AsbestosSuitOn>

149 David Burdett Email dated 8/21' We should use "communication protocol" rather than "transport" or "transport protocol" when we are referring to the likes of HTTP or SMTP. Lines where this applies are: 101, 102, 121, 152, 153, 180, 181, 182, 184, 186, 187 (twice), 189 (twice), 521, 1317, 1327, 1338 (transport level requirement)  
150 David Burdett Email dated 8/21' Envelope vs Container. These are used ambiguously. For example, the diagram on page 7 suggests that the ebXML (header or payload) container and the envelope are the same. However the examples on lines 273-280 (header) and lines 325-332, indicate that the "header" is the MIME header for the mime part. Suggest we add the following definitions after the diagrams on page 7:                                                       "* An ebXML Header (or Payload) Envelope are the MIME headers that are associated with a MIME part                                                         * An ebXML Header (or Payload) document is the content of the MIME part and is:                                                                                                                                                       - an XML document for the ebXML Header, and                                                                                                            - an XML or some other document for the ebXML Payload * An ebXML Header (or Payload) container, is the combination of the ebXML Header (or Payload) envelop and the document it contains" 3. Appendices C & D Why are these included within the spec. I think that they should be removed as it makes the spec shorter and they are non-normative. However I don't think the information should be lost. It should be included in a non-normative "rationale" document that explains how decisions were made for those people who are new to ebXML TRP.  
151 Henry Lowe Email dated 8/21 ROUTING This is not unrelated to the issue of routing.  This document says nothing about how routing is handled or reflected in the message header.  If we are using source routing (i.e., the message originator or perhaps the TPA defines the route the message will take to the destination).  Presumably a full set of source routing information will need to be contained in the header or perhaps in subheaders containing the route when the route comprises more than a single hop.  This set of routing information would have to contain the necessary "context" for each transport in the case of different transports being used for different hops, e.g., hop-1 uses HTTP, hop-2 uses CORBA, hop-3 uses MQSeries, and hop-4 uses SMTP (OK, perhaps this is a bit complicated, but the  header information structure should be able to support this  heaven knows what the real world may turn up).  
152 Marty Sachs Email dated 8/22  GENERAL Some of the dicussions about interrelations between Reliable Messaging and transport protocols point up the need to state the assumptions about the transport function in some manner.  One possibility is some kind of definition of a conceptual interface between the Messaging Service and the transport function.  It's fine to say that the messaging service is agnostic to the transport protocol but in real life, the Messaging Service run-time must interact with the transport run-time. Design of the messaging service protocol must be with the understanding of what goes on in the most likely transports.  Since it is highly likely that an implementation will include both the messaging service and the transport function, it may be  sufficient to express the interactions as a series of informative notes (or an informative appendix) rather than as a formal interface definition. The important point is that the assumptions have to be stated to ensure that the messaging service and transport function will work together correctly.  
153 David Burdett Email dated 8/21  Appendix B Suggest removing the detail of the XML documents to make the examples much shorter.  
154 David Burdett Email dated 8/21  GENERAL Add titles to all figures.  
155 David Burdett Email dated 8/21  GENERAL Use capitals consistently, specifically:   i) "ebXML header document" -> "ebXML Header Document"   ii) "ebXML header envelope" -> "ebXML Header Envelope"

157 Dick Brooks email dated 8/14      General version' is in the Content-type header of the ebXML header and in the ebXMLHeader root element of the ebXML header document.  I should be in only one place.  
158 Dick Brooks email dated 8/14      General we need to provide a complete list of possible values for the 'content' attribute within the PartyId element.  
159 Dick Brooks email dated 8/14      General The MessageData element should also include a 'DeliveryDeadline' element which indicates the last instance in time a message can be delivered to an intended recipient and a 'ResponseDeadline' element to tell the receiver how long they have to send an acknowledgment.  I believe it would also be valuable to indicate how an acknowledgment should be sent on the same session that was used to send the ebXML message.  If the AcknowledgeTo element is not present then whatever was specified in the TPA determines how acknowledgments are delivered.  
160 Shumpei Nakagaki email dated 8/16        Appendix B          Line 801-803, 1064-1067 The Appendix B shows the ebXML Message envelope message example only.  The spec is for the envelope and header. Line 801 thru 803 and line 1064 thru 1067 should be replaced with:                                                                                                                          <MessageType>Normal</MessageType><Manifest><DocumentReference><DocumentLabel>Payroll</DocumentLabel><Intent>RecordCommission</Intent></DocumentReference></Manifest><Header><From><PartyId context="DUNS">12345</PartyId></From><To><PartyId context="DUNS">67890</PartyId></To><TPAInfo><TPAId Context="tpadb">12345678</TPAId><ConversationId context="tpadb">987654321</ConversationId><ServiceInterface>RecordCommission</ServiceInterface><Action>Newrecord</Action></TPAInfo><MessageData><MessageId>123456789</MessageId><TimeStamp>20000725T122905.000Z</TimeStamp><RefToMessageId>987654321</RefToMessageId></MessageData><ReliableMessageInfo><DeliverySemantics>"Unspecified"</DeliverySemantics></ReliableMessageInfo></Header>  
161 Marty Sachs Email dated 8/22   Appendix B Both of the example XML files in Appendix B need to be updated to conform to the new header definitions, both <ebXMLMessageHeader> and <Header>.  The DTD and Schema appear to be OK.
