Done, plus some more editing, here's the result in my working draft:

   A WebRTC application may use one or more RTP streams, as discussed
   above.  In addition, it may include an SCTP-based data channel
   [I-D.ietf-rtcweb-data-channel] whose QoS treatment depends on the
   nature of the application.  For example, best effort treatment of
   data channels is likely to suffice for messaging, shared white board,
   and guided browsing applications, whereas latency-sensitive games
   might desire better QoS for their data channels.
