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.
