FWIW, we Jabberites used https URIs like http://jabber.org/protocol/* for a long time but recently switched to URNs like urn:xmpp:* because they're more stable (what happens if the person registering jabber.org loses control over the domain?) and will last forever. The choice of http URI vs. URN seems like a toss-up to me. Peter -- Peter Saint-Andre https://stpeter.im/
