[Jean-Francois Mule <[e-mail]>]

John,

  I cannot find an email to the mmusic list indicating that the chairs intended to make draft-garcia-mmusic-sdp-misc-cap-01 a working group item and asking for any objections or comments.  Like Simo, I was convinced we had agreed to make this a wg item and did not check before approving the request when the ID was proposed in early March 2010.  This is of course contradictory to our process.

  Mea culpa - we will discuss at the meeting how to proceed on that.

  I will provide more comments on the rest of this email in a separate note as an individual contributor.

Jean-Francois
MMUSIC co-chair
