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:18.104.22.168.4.1.6320 is another possibility altogether
