Actually, so far, pretty much everyone seems to have implemented
namespaces this way, and it's working like a charm: it's standard in
the very popular Perl XML:Parser module (which uses Expat), I wrote my
own SAX filter (unreleased) which works this way, John Cowan has
released a SAX filter that works this way, and I assume that all RDF
and XSL tools built on top of SAX work this way.

I rely quite heavily on the namespace processing in XML::Parser for
some of my production-grade deliverables to customers.


All the best,


David
