RE: XMPP IRIs: feedback requested

Maybe we should address this in the URI scheme registration
document--that schemes could be defined in terms of "IRI" syntax,
using RFC 3987 rules to transform them to URI syntax.

Right now, the guidelines don't really mention that as
a possibility. 

Even so, it should still be called a "URI scheme", even
if it is defined using "IRI syntax".

Looking at RFC 3920, does the xmpp URI scheme assume
that you're using the TCP binding? Would there be a different
scheme for a binding that uses polling over HTTP?
Is the "xmpp" scheme only for XMPP version 1.0, or is
the version negotiated independently?
