    abstract =  {This document describes a protocol extension for the HTTP-Enabled Location Delivery (HELD) protocol. It allows a Target to manage their location information on a Location Information Server (LIS) through the application of constraints invoked by accessing a location URI. Constraints are described that allow control over how long the URI is valid for and the access policy used when a location URI is accessed.},
