Subject: [MMUSIC] Mail regarding draft-ietf-mmusic-sdp-srcfilter

Hello there,

I've just been looking at RFC 4570 on SDP source filters, and think there might be a minor error in the IPv6 example. I originally tried contacting the RFC authors, but the email address listed on the RFC tracker page bounced.

The normative text on page 3 states:

"""

   The source-filter attribute has the following syntax:

       a=source-filter: <filter-mode> <filter-spec>

"""

However the IPv6 example on 7 reads:

a=source-filter incl IN IP6 FF0E::11A 2001:DB8:1:2:240:96FF:FE25:8EC9

Which is missing a colon after the "source-filter" entry, and as such should read:

a=source-filter: incl IN IP6 FF0E::11A 2001:DB8:1:2:240:96FF:FE25:8EC9

Kind regards,
