> Abstract:
>     Real-time text mixers for multi-party sessions need to identify the
>     source of each transmitted group of text so that the text can be
>     presented by endpoints in suitable grouping with other text from the
>     same source.
>
>     Regional regulatory requirements specify provision of real-time text
>     in multi-party calls.  RFC 4103 mixer implementations can use
>     traditional RTP functions for source identification, but the mixer
>     source switching performance is limited when using the default
>     transmission characteristics with redundancy.
>
>     Enhancements for RFC 4103 real-time text mixing is provided in this
>     document, suitable for a centralized conference model that enables
>     source identification and source switching.  The intended use is for
>     real-time text mixers and multi-party-aware participant endpoints.
>     The specified mechanism build on the standard use of the CSRC list in
>     the RTP packet for source identification.  The method makes use of
>     the same "text/red" format as for two-party sessions.
>
>     A capability exchange is specified so that it can be verified that a
>     participant can handle the multi-party coded real-time text stream.
>     The capability is indicated by use of a media attribute "rtt-mixer".
>
>     The document updates RFC 4103[RFC4103]
>
>     A specifications of how a mixer can format text for the case when the
>     endpoint is not multi-party aware is also provided.
