ok - cool, I can run with that. I believe this will directly clear up
John Elwell's (and others) confusion about the many forms of Geopriv
entity roles.

I have a more meta question that's a hole in the above "inserter" role though:

what is the role of the SIP server that inserts a location URI of
the Target?

that's gotta be defined somewhere. I believe this entity is also an
LS, because it is a location aware entity that is sighting (put aside
the fact that you hate that word) the target. This "act of sighting"
is location awareness - ergo an entity role within Geopriv
architecture. This entity would _not_, however, be an LG (that's
saved for LO creators, which this entity does not do).
