Thanks, I just hadn't thought of that, i.e. that (namespace,localname) is just a pair. > One thing I've noticed in the hash vs slash discussion is that '=' > and '?' are rarely talked about as suitable final characters for > namespace URIs.

Maybe the reason for not using such namespace URIs is that their semantics is less well defined than what Shane recapitulated for / and #. IIRC, it's basically up to the web server application how to interpret such URLs. Cheers, Christoph -- Christoph Lange, Jacobs Univ. Bremen, http://kwarc.info/clange, Skype duke4701
