Right. You would want a format that is as close as possible to what RFC
And that in turn refers to GML 3.0 for the non-civic forms of location.
I see a small possibility in XEP-0080.
The last element is an URI.
That could be used as a pointer to a location by reference in the RFC
It seems that RFC 6442 prefers location by reference for the SIP case,
so that may be the case for XMPP as well.
