Thanks - it's good to know that there are horrors in RFC 2396 which I
have been lucky enough not to encounter (yet).

RFC 2396 is a remarkable document.  Holy writ and hellish mess all
wrapped into one package.  Separating the two is difficult, both in
theory and in practice.

I've stopped using the term "URI" except in cases where it is purely an
identifier - namespaces and RDF are the only two places I know of where
that usage feels comfortable.  Otherwise I'm back to URLs.

Simon St.Laurent - SSL is my TLA
http://simonstl.com may be my URI
http://monasticxml.org may be my ascetic URI
urn:oid:1.3.6.1.4.1.6320 is another possibility altogether
