Existing Open Issues
Should a Proxy somehow label its location information in the proposed 425 (Retry Location Body) message?
a PIDF-LO question?
Still have not determined if/how a UAC can request the UAS return its location in a 1XX or 2XX response
maybe just use a SUB/NOT (if supported)?
Still have not determined if a Redirect model should be accounted for (if the 3XX response includes LI, does that get included in the new/next Request by the UAC?)
