Subject: RE: Repurposing version attributes E: [ebxml-cppa] CPP and CPAelementdocumentation changes
It seems more useful to identify the version of the schema than the version
of the spec.
In a CPP/A instance, there already is a
xmlns:tp="http://www.oasis-open.org/committees/ebxml-cppa/schema/cpp-cpa-2_0
.xsd"
declaration. I think the above namespace URI implies the version of the
spec, but the version of the schema is not indicated anywhere.

I believe that when this was last discussed, we were assuming that the
version of the spec and the version of the schema are the same. If we
start making maintenance changes in the schema between versions of the
spec, this must somehow be indicated in the instance documents so the two
parties know they are working with the same schema.

Marty
