This looks more like a comment by you suitable for the W3C XML Schema group to deal with, or should be made into such a comment, asking them specific questions. It could also be feedback into XSD 1.1 requirements. As to the content, it seems OK however the issue of URIs for XSD types is already something the Schema WG has to address: [[[ # the definition of a free-standing specification describing how to name or refer to arbitrary components in an XML Schema; in existing discussions these are sometimes referred to as normalized universal names or NUNs ]]] -- http://www.w3.org/2001/12/xmlbp/xml-schema-wg-charter.html See also: TAG issue: http://www.w3.org/2001/tag/ilist#rdfmsQnameUriMapping-6 Discussion: http://lists.w3.org/Archives/Public/www-xml-schema-comments/2002OctDec/0011.html and (member only) draft (1 Oct 2002): http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002Oct/att-0050/01-part However I can't see it in the XSD 1.1 candidate requirements (member only) http://www.w3.org/XML/Group/2002/07/xmlschema-1.1-current-reqs.html [ Why is this all member only? ] In particular this is testing somebody elses specification again (like with xml:base) and we should try to avoid this. This analysis certainly should not be normative text in our specifications at this stage. If there is anything to add to the Concepts WD, maybe it would be to spell out the exact requirements for datatypes used in RDF datatyping, some of which is in the introduction to the above. Maybe near http://www.w3.org/TR/rdf-concepts/#section-Datatypes ? Dave
