Dear Colleagues

The RDF Core WG has considered your last call comment captured in

    http://www.w3.org/2001/sw/RDFCore/20030123-issues/#xmlsch-10

(raised in section
  "4.4. Normative specification of XML grammar (policy, substantive)" of
http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0489.html )

and decided

    http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Apr/0361.html

to postpone it.

A canonical subset of RDF/XML was considered by the RDF Core WG.
However the WG believes that due to the way mixed namespaces are used
in RDF/XML it is not possible to define such a subset that:

  a) can represent all the RDF graphs that RDF/XML can represent
  b) can be described by an DTD or an XML Schema.

An alternative would be to define a new syntax that is describable
with a DTD or an XML Schema but doing so is beyond the scope of RDF
Core's current charter.  We note that the XHTML WG have expressed
interest in working on such a syntax and have been encouraged to do
so by RDF Core.  RDF Core also welcomes XML Schema's offer to help
with this work.

We will add this issue to the RDFCore postponed issues list at:

   http://www.w3.org/2000/03/rdf-tracking/#rdfms-validating-embedded-rdf

Please reply to this email, copying www-rdf-comments@w3.org indicating
whether this decision is acceptable.

Thanks

Dave
