A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group of the IETF.

	Title		: An Extensible Markup Language (XML) Representation for Expressing Policy Capabilities
	Author(s)	: J. Rosenberg

An important component of presence and location services is policy.
Policy systems allow the presentity or location target to grant
access to specific pieces of information to specific watchers or
requestors.  These policy systems can be extremely simple, allowing a
user to accept or block requests based solely on the identity of the
requestor, to extremely complex, allowing for time based rules that
grant or deny specific pieces of information.  Policy systems often
support vendor proprietary features.  To allow for interoperability
between clients which set such policies, and servers which execute
them, it is necessary for clients to be able to determine the
capabilities of the server to which it is connected.  This
specification defines an Extensible Markup Language (XML) based
format for expressing such capabilities.

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.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
