  A clearer summary of what I'm trying to say: if you expect "geo:" URIs 
to be used in SIP location conveyance, you'll need to explicitly add 
text saying so.

The bit about them being forbidden was based on assertions from people 
who know far more about geopriv than I do -- they asserted that it 
lacked the "priv" half of "geopriv," and therefore wasn't appropriate. 
Martin (or Richard, I can't recall) has proposed some ways this might be 
fixable, and I have no opinion on that topic.
