Hello,
A new version of the SDP capability neg extensions for "b=" and "i=" lines is now available at:
http://www.ietf.org/internet-drafts/draft-mmusic-sdp-icap-bcap-01.txt

Changes in this version are:
- clarified the usage of bcap and icap attributes when declared at session level vs. at media level (they now result in session level, and media level b/i-lines, respectively)
- added an Offer/answer section
- added some text to security considerations
- editorial cleanup

Regards,
Simo

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title           : Title and Bandwidth Capabilities Negotiation in the Session Description Protocol (SDP)
	Author(s)       : M. Garcia, et al.
	Filename        : draft-mmusic-sdp-icap-bcap-01.txt

SDP has been extended with a capability negotiation mechanism framework that allows the endpoints to negotiate transport protocols and attributes.  This framework has been extended with a media capabilities negotiation mechanism that allows endpoints to negotiate additional media-related capabilities.  This negotiation is embedded into the widely-used SDP offer/answer procedures.

This memo extends the SDP capability negotiation framework to allow endpoints to negotiate two additional SDP capabilities.  In particular, this memo provides a mechanism to negotiate titles ("i="
line for each session or media) and bandwidth ("b=" line).
