Namespaces and Parsers
I have been re-reading the namespace draft (I am a fan of namespaces!) as a prelude to making JUMBO2 namespace-aware. I note that they are very closely bound to the parsing process (WD-xml-names-1998-03-27): '[the WG intends that] this namespace facility should become an integral part of some future version of the XML spec.' I suspect that the namespace draft will harden up before a future version of XML (comments from WG?) and if so there are some technical requirements for parsers. The draft gives a number of validity conditions (e.g. the namespace declarations must precede the external and internal subsets). I suspect that this positional and other validation information will be lost in the output of many parsers (including SAX-compliant ones). Should the current generation of parsers address the *syntactic* aspects of namespaces? i.e. should it be possible to use a parser to: - recover the namespace declarations and their components - be notified of namespace validation errors If the answer is 'yes', should this be part of the next version of SAX? My immediate feeling is that it shouldn't be difficult (the NS draft is pretty straightforward syntactically) and it's highly desirable. A processNamespace() callback would save application writers for yet another place where bugs and misunderstandings could creep in. P.
