All, This document has a number of updates based on AD review and other reviews which are summarized below. The changes are based on changes since the -09 version from December. Comments are most welcome! Thanks to everyone for their reviews and feedback. - Alan - - Changed conflicting text on <exclusive> element. True means the call/dialog cannot be replaced or joined. The default is False if not specified. - Added missing normative text on the usage of the 'shared' event parameter. - Clarified that UAs do not insert appearance parameter into Alert-Info - Clarified what happens if a UA in group sends an INVITE to the group AOR. This uses two appearance numbers. - Removed text about proxies removing Alert-Info header fields - Clarified that subscriptions and publications must be authorized. - Made security considerations text consistent with that in Replaces and Join RFCs. - Added IANA section on registration of 'appearance' parameter to Alert-Info header field - Fixed error in URN registration On Fri, Jun 8, 2012 at 1:26 PM, <internet-drafts@ietf.org> wrote: > > A New Internet-Draft is available from the on-line Internet-Drafts > directories.
