Just to head off one possible objection... that of the persistence (or
lack of) w.r.t. http URLs. The PURL folks (Persistent URLs) make a
credible case when they argue that URLs can be managed just a
responsibly as URNs, and that persistence of http naming is a social
issue not a technical one. PURL servers are available to help here -- eg
XML-DEV's own XSchema (now DDML) pages have been available from several
different http servers, but have always had the same URI:
http://purl.oclc.org/NET/xschema  
The PURL server at that address sends an HTTP redirect messge if you try
to derefence it. So we could for eg use PURLs to name software features,
with reassurance that PURL.ORG have committed to do their best to manage
http://purl.org/* names responsibly.

Yep.
