Internet-Draft Geopriv Policy Capabilities April 2005
1. Introduction
Authorization policies are an important component of presence
[RFC2778]. They allow the presentity to grant access to specific
pieces of information to watchers. Authorization policies have been
designed to be extensible. For this reason [I-D.rosenberg-simple-
common-policy-caps] defines a generic Extensible Markup Language
(XML) based format for representing policy capabilities. That format
applies to many policy types, including location and presence. This
specification extends that one by defining policy capabilities
specific to geographic location information. Those policy
capabilities correspond to the conditions, actions and
transformations defined in [I-D.ietf-geopriv-policy].

2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].

3. Structure of Geopriv Policy Capabilities
The structure of common policy capability documents is defined in
[I-D.rosenberg-simple-common-policy-caps]. In that specification,
each policy capability document has three components - a list of
supported conditions, a list of supported actions, and a list of
supported transformations. This specification merely extends that
document with the conditions, actions and transformations defined in
[I-D.ietf-geopriv-policy]. It does so by defining the following
empty elements:
civic-loc-condition
geospatial-loc-condition
distribution-transformation
retention-tranformation
keep-rules-transformation
civic-loc-transformation
geospatial-loc-transformation
Each of these elements indicates whether the respective attribute in
[I-D.ietf-geopriv-policy] is supported. All of these elements are
defined within the namespace:
urn:ietf:params:xml:ns:geopriv-policy-capabilities
