Technical Summary

The Presence Information Data Format Location Object (PIDF-LO)
specification provides a flexible and versatile means to represent
location information.  There are, however, circumstances that arise
when information needs to be constrained in how it is represented.  In
these circumstances the range of options that need to be implemented
are reduced.  There is growing interest in being able to use location
information contained in a PIDF-LO for routing applications.  To allow
successful interoperability between applications, location information
needs to be normative and more tightly constrained than is currently
specified in the RFC 4119 (PIDF-LO).  This document makes
recommendations on how to constrain, represent and interpret locations
in a PIDF-LO.  It further recommends a subset of GML that is mandatory
to implement by applications involved in location based routing.
