WG,

The authors have updated the draft to address the review comments 
received. The changes are:

    o  Added section on RTP Aspects

    o  Added a requirement (5-4) on that capability exchange must be
       capable of handling multi RTP stream cases.

    o  Added extmap attribute also on first signalling example as it is a
       recommended to use mechanism.

    o  Clarified the definition of the simulcast attribute and how
       simulcast streams relates to simulcast formats and SCIDs.

    o  Updated References list and moved around some references between
       informative and normative categories.

    o  Editorial improvements and corrections.

I will also note that during the editing we found one more issue. We 
will send separate email on this to try to resolve that issue.

Especially the first change is quite a bit of new text, so I hope that 
people can review this in by the end of the IETF meeting when we expect 
to update the document again.

Cheers

Magnus

> Abstract:
>    In some application scenarios it may be desirable to send multiple
>    differently encoded versions of the same media source in different
>    RTP streams.  This is called simulcast.  This document describes how
>    to accomplish simulcast in RTP and how to signal it in SDP.  The
>    described solution uses an RTP/RTCP identification method to identify
>    RTP streams belonging to the same media source, and makes an
>    extension to SDP to relate those RTP streams as being different
>    simulcast formats of that media source.  The SDP extension consists
>    of a new media level SDP attribute that expresses capability to send
>    and/or receive simulcast RTP streams.
