	Title		: Session Authorization Policy Element

This document describes the representation of a session authorization
policy element for supporting policy-based per-session authorization
and admission control.  The goal of session authorization is to allow
the exchange of information between network elements in order to
authorize the use of resources for a service and to co-ordinate actions
between the signaling and transport planes.  This document describes
how a process on a system authorizes the reservation of resources by a
host and then provides that host with a session authorization policy
element which can be inserted into a resource reservation protocol
(e.g. the RSVP PATH message) to facilitate proper and secure
reservation of those resources within the network. We describe the
encoding of session authorization information as a policy element
conforming to the format of a Policy Data object (RFC-2750) and provide
details relating to operations, processing rules and error scenarios.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
