RE: [Geopriv] Message Flow

But that wouldn't let the recipient get updated location, right?  So it
wouldn't generally be useful.  To be useful, it would have to have both a
snapshot and a "regular" reference, send both and mark them appropriately.

The context draft doesn't match the syntax of -conveyance, which means we
have information loss from the proxy to the recipient.  That means "mark
them appropriately" is hard.
