The intent for xmpp URIs was that on the rare occasions that <authority> 
  is included, it must be followed by either nothing ("authenticate as 
this user") or slash and path then optionally <query> and/or <fragment> 
("authenticate as this user and generate an XMPP stanza directed to the 
address specified in the path"). Unfortunately, it seems that my ABNF fu 
was not strong enough to capture that properly. The use of <authority> 
in xmpp URIs is quite specialized, I doubt it will be used much if at 
all, and it is confusing in several ways that I don't particularly like, 
but it was specifically requested when we defined the scheme. In any 
case, I will determine the appropriate corrections and submit them as 
errata (with submission of rfc4622bis likely to follow in concert with 
rfc3920bis and rfc3921bis).

Yes, that's the plan.
