Location-to-Service Translation (LoST) Service List Boundary Extension

Location-to-Service Translation (LoST) maps service identifiers and location information to service contact URIs. If a LoST client wants to discover available services for a particular location, it will perform a <listServicesByLocation> query to the LoST server. However, the LoST server, in its response, does not provide context information; that is, it does not provide any additional information about the geographical region within which the returned list of services is considered valid. Therefore, this document defines a Service List Boundary that returns a local context along with the list of services returned, in order to assist the client in not missing a change in available services when moving. This document defines an Experimental Protocol for the Internet community.
