This will never happen. The namespace URI is just a name. It would be really wrong to assume you can go there and get a DTD, because: 1. some namespaces (like HTML, MathML, a few others) are going to be very widely used, and it would be silly to force one poor server somewhere to guarantee a DTD-on-demand for them 2. some namespaces aren't going to have DTDs or any other kind of schema 3. some schemas aren't going to be DTDs For all of these reasons, the namespace name has to remain just that: a name. We are obviously going to need ways to find schemas associated with namespaces. SGML/XML have a way of doing this, the <!DOCTYPE declaration, but it can only really point to one DTD at a time. Presumably future schema proposals will have ways of pointing to multiple parallel schemas. -Tim xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
