IIRC we had that as a MUST in an earlier version of XMPP Core but I'd
have to look through CVS to find it. I know we've talked about SHOULD
vs. MUST for id attributes on IQ stanzas, and it sounds like we may need
to think about it some more. I would have no problem making that a MUST
but this is not the forum for such a discussion. :)
