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 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 Geography Markup Language (GML) 3.1.1 that is
mandatory to implement by applications involved in location-based
routing. [STANDARDS TRACK]
