The Presence Information Data Format - Location Object (PIDF-LO) provides the geographical location of a presentity. This corresponds to a physical location at a given instance of time. PIDF-LO provides an XML formatted “location object” that is included in the SIP Invite of an emergency call to provide the location information. PIDF-LO supports dynamic location routing (DLR).
