This document defines an authorization policy language for
controlling access to location information.  It extends the Common
Policy authorization framework to provide location-specific access
control.  More specifically, this document defines condition elements
specific to location information in order to restrict access based on
the current location of the Target.

Furthermore, this document defines two algorithms for reducing the
granularity of returned location information.  The first algorithm is
defined for usage with civic location information while the other one
applies to geodetic location information.  Both algorithms come with
limitations, i.e. they provide location obfuscation under certain
conditions and may therefore not be appropriate for all application
domains.
