Summary: This document is ready for publication as a Proposed Standard
RFC.  I have a few minor comments that should be considered s they may
improve future understanding of the document.

Major issues: None

Minor issues:
    In reading section 4.2 and 4.3, I believe I can guess at certain
intended behaviors, but it is not as clearly stated as I think is
desirable.  There is also one odd statement in section 4.3

    Taking the odd statement first, the text in section 4.3 refers the
active answerer "towards
   the IP address and port of the offerer".  But when WebSockets is
used, one does not connect to the IP address and port, but to the URI

    I believe that the intent in 4.2 and 4.3 is that whichever side
will be "passive" is required to provide an a=ws-uri or a=wss-uri so
that the other side can establish the connection to the URI.  But
section 4.2 does not say that.  And the text in section4.3 that talks
about providing the URI in the a= does not qualify whether it is
required with active, passive, or both.  

Nits/editorial comments:  N/A
