Interestingly, Part 7 of the discussions for ISO DSDL (Document Schema Description Language) is "Namespace-aware processing with DTD syntax". Presumably that would rubberstamp the namespace idea, since it has proved itself to a significant user-base, and remove any objections based on standards for ifever W3C wanted to make DTDs namespace-aware, say in XML 2.0, when that eventuates. Part 7 has no editor yet, so I guess it is a slot indicating that the ISO WG 34 does not want to get in the way of any good progress rather a promise. Another reason for namespace-aware DTDs is that then these can be regarded as abbreviated, limited syntaxes for XML Schemas or RELAX NG. I think James had that interesting tool which maps all uses of parameter entities to RELAX NG. Presumably, apart from entity references, the one thing that DTDs have that XML Schemas (and RELAX NG) do not reconstruct is conditional sections. For conditional sections in DTDs (all that XML allows), I think that Schematron's phase mechanism suffices: I wonder whether phases could be grafted onto RELAX NG?
