	Title		: SDP attribute for qualifying Media Formats with 
                          Generic Parameters

This document defines a new SDP attribute called general-purpose 
media descriptor (gpmd).  The gpmd attribute allows the use of new 
informative parameters, gpmd parameters, to qualify existing media 
formats.  These gpmd parameters are not part of the standard (e.g., 
MIME) definition of the media format and support for them with a 
given media format can therefore not be assumed.  Their use is 
therefore limited to cases where they provide information that may be 
of use to the other party in a session but is not critical to the use 
of the particular media format.  This document also defines a 
specific gpmd parameter, voice-band data, which can be used to 
describe a media format as carrying voice-band data. This enables the 
receiver to optimize its handling of the media received.

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.
