Re: I-D ACTION:draft-ietf-sip-location-conveyance-05.txt

"The entities receiving location MUST obey the privacy and security rules in 
the PIDF-LO as described in RFC4119, regarding retransmission and 
retention."

Does this mean that a SIP proxy receiving a request with a Geolocation must 
first inspect the location object before forwarding? For 
location-by-reference, this may introduce an unacceptable delay, especially 
when the proxy does not do anything with the location information itself.

Proxies that don't understand Geolocation will forward as usual, possibly 
violating the forwarding policy. You may want to spend some words on this. 
For proxies that do understand, you could consider inserting a flag in a SIP 
Geolocation header for the by-reference case, such that a dereference is not 
needed to obtain the policy
