RE: XML Schema or DTDs?

[Stuart Campbell <stuart.campbell@tieglobal.com>]

I agree with Joel.  Worse i think in some specs there are even statements
(and indeed the requirements document) that we should only stick to open
standards and then, as such, thats why in that spec they focus on DTDs.  I
raised this issue at the closing plenary although it was out of context in
the TRP/SOAP discussion.

My belief is that we should be consistent and we should recognise that
schemas are just round the corner (aren't they always!).  On this basis all
specs should be upgraded to be consistent with schema and the DTD's can be
just informative (if needed at all).  Im not sure of the impact of this, but
i imagine its great so something to add to the next round i guess

Subject: XML Schema or DTDs?



Please clarify a simple thing for me.  Is ebXML Specifying XML Schemas or
DTDs?  I have asked this question before and have never received a clear
answer.  Should this be consistent throughout ebXML?  Of the two teams that
I have monitored and contributed to, I note that Reg/Rep has defined DTDs
and TR&P has defined Schemas.  What about the other teams?

Ref: 0.98 TR&P Spec
Appendix A ebXML SOAP Extension Elements Schema
The following is the definition of the ebXML SOAP Header extension elements
as a schema that
conforms to [XMLSchema]. This schema is a normative definition of the ebXML
SOAP extension
elements. Section 8 details the normative specification for these elements.

Ref: 0.88 Registry Services Specification
Appendix A Schemas and DTD Definitions The following are definitions for the
various ebXML Message payloads described
in this document.
A.1 ebXMLError Message DTD
See [ERR] for ebXMLError Message DTD.
A.2 ebXML Registry DTD
