This update addresses all received comments:

   o  Correcting syntax of SDP examples in section 6.6.1, as found by
      Inaki Baz Castillo.

   o  Changing ABNF to only define the sc-value, not the SDP attribute
      itself, as suggested by Paul Kyzivat.

   o  Changing I-D reference to newly published RFC 8108.

> 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.
