	Title		: Source-Specific Media Attributes in the Session Description Protocol (SDP)
	Author(s)	: J. Lennox, et al.

The Session Description Protocol provides mechanisms to describe
   attributes of multimedia sessions and of individual media streams
   (e.g., Real-time Transport Protocol (RTP) sessions) within a
   multimedia session, but does not provide any mechanism to describe
   individual media sources within a media stream.  This document
   defines a mechanism to describe RTP media sources, identified by
   their Synchronization Source Identifiers (SSRCs), in SDP, associate
   attributes with these sources, and express relationships among
   sources.  It also defines several source-level attributes which can
   be used to describe properties of media sources.

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.
