Does anyone know where the the latest IETF draft is?
I can't find anything about the uuid: scheme under the
URN working group area or the "Individual Submissions"
area, and a keyword search for "uuid" doesn't turn
anything up.  Has the draft expired?

The UUID scheme would solve a real problem I've been having
wrt. inventing namespace URIs: "[t]he namespace name, to
serve its intended purpose, should have the characteristics
of uniqueness and persistence." [Namespaces, section 2].

Uniqueness I can handle -- the organization behind flightlab.com
is small enough that there's little chance of conflict if
I use an 'http:' URL (and besides, I'm the only one here who
really does much with XML anyway), but persistence is another
matter altogether.

Using the http: scheme for persistent URIs is all well and good for
the W3C, but you'd think they'd know better than to recommend
it as a general solution for everyone else after having gone
through the info.cern.ch -> mit.edu -> w3.org transition.
