RE: [bt-spec] URIs and address-as-X (MAJOR)

Jim,

I was working on a longer reply, and realised we may have a terminological
crossed-wire, which needs straightening out.

(I've assumed it was only by mistake that you didn't cc bt-spec)

I'd missed :

When you say "URI" do you really mean URI in the strict sense, or only URL -
or even just http URL ?

URI is the super-set of URNs and URLs. URNs are names, which identify but do
not locate (e.g. the urn for teh BTP xml namespace).  URLs always locate,
but by reference to particular protocols (so
mailto:peter.furniss@choreology.com ,
tip:vivaldi.inria.fr/ssdjfk/ksd?xyzzy.678 and
http://www.oasis-open.org/committees/business-transactions/issues.html#Issue
99 are urls )  (Actually there are some non-locating URL schemes, but I'm
not sure if any have been officially registered)

The proposed solution to 78 really does mean URI - and would expect URNs to
be quite common or even preferred.

Once I'm sure we're using the same terms for the same set of things, I've
more to say.
