Specifying use of a profile with CPP

["Stephen Green" <stephen_green@bristol-city.gov.uk>]

Greetings

I've some questions about ebXML CPP in relation to UBL as an ebXML payload.


1. For someone using UBL Lite as a profile, is it possible to specify use of a profile in CPP?
Using the CPP Schema, tp:NamespaceSupported element I can specify:

<tp:NamespaceSupported tp:location="UBL-Order-1.0.xsd" tp:version="ubl-lite-0.2">urn:oasis:names:specification:ubl:schema:xsd:Order-1.0</tp:NamespaceSupported>

but I imagine it might not be proper to use the tp:version attribute in this way

Also, in the above example it seems the emphasis is on the location of the Schema rather than the namespace;
the example CPP document given actually uses the Schema location in the text of the element too. I took the
liberty of using the namespace of the UBL document in the element text content but is this correct?
UBL doesn't yet have a permanent  loaction so I'm perturbed at the emphasis on location in what should be
by definition a specification of support of a namespace rather than a physical Schema file.



2. Does one have to wait for an official BPSS definition of UBL processes to be defined in order to use UBL with CPP?

How can I get appropriate values for:

<tp:ProcessSpecification tp:version="**" tp:name="*******" xlink:type="simple" xlink:href="*****" tp:uuid="******"/>

in order to specify use of UBL in my CPP document?



3. Pushing this further, what would be required in order to specify use of a defined subset/profile of UBL such as UBL Lite?
I would imagine something like
<tp:ProcessSpecification tp:version="2.0" tp:name="ubl-lite-0.2" xlink:type="simple" xlink:href="http://lists.oasis-open.org/archives/ubl-dev/200409/msg00002.html"; tp:uuid="*******"/>
but this would be a desparate measure and it still doesn't give me a tp:uuid. 



4. ** Does this all mean we can't use CPP without there having been substancial BPSS and registration work already done at a standards level? **




I'd appreciate any help or comments
