As one of the authors of 3470 I can say very clearly that 3470 doesn't provide advice on this point. It states fact: "Typically (and recommended practice in W3C) is to assign namespace names using persistent http URIs." Notice that there's no "may", "should", "must", etc. > Thus, if it's considered A Good Thing to provide a > description of the namespace *at* the namespace URI - and > when would it not? - I'd suggest to still use an http based > namespace URL. > > There are some IETF specs that for that very reason use URI > assigned by the W3C (Atom, Atompub), and lots of other IETF > specs use URIs on purl.org. That's certainly a valid option. I'm not saying that one is better than the other. What I am saying is that people shouldn't think that 3470 recommends one over the other. -Scott-
