Speaking as W3C XML Activity Lead :-) I don't see a reason to give XSD special status in that way. W3C XSD has a lot of uses, and works well if you are also using XSLT 2, XQuery, Web Services or other specifications where the XSD support is well-integrated. This doesn't in any way preclude using RelaxNG, DTDs, Schematron, or any other sort of validation, and it's not really the place of the XML specification to give a list of other technologies that are used with it or build on it. As Tim and others said, DTDs are in the XML specification for historical reasons. If we had the resources, I can certainly imagine refactoring XML 1.0 to put DTDs into a separate document, and to bring into that document namespaces and xml:base and maybe others. But the work of doing that is much greater than it sounds -- making sure the text retains the same meaning, and even that documents referring to specific productoins in the EBNF grammar are not broken as a result. So I don't expect much enthusiasm for making a new edition of XML to make the Informative References include XSD, but please don't take that as a negative statement about XSD :-) Liam -- Liam Quin, W3C XML Activity Lead, http://www.w3.org/People/Quin/ http://www.holoweb.net/~liam/ * http://www.fromoldbooks.org/
