The Location-to-Service Translation (LoST) protocol is an XML-based
protocol for mapping service identifiers and geodetic or civic
location information to service URIs and service boundaries.  In
particular, it can be used to determine the location-appropriate
Public Safety Answering Point (PSAP) for emergency services.

The main data structure, the <mapping> element, used for
encapsulating information about service boundaries is defined in the
LoST protocol specification and circumscribes the region within which
all locations map to the same service Uniform Resource Identifier
(URI) or set of URIs for a given service.

This document defines an XML protocol to exchange these mappings
between two nodes.  This mechanism can be used for bulk exchange of
<mapping> elements between two entities.  As such, this document can
also be used without the LoST protocol.
