Thank you for the updated document Suhas. I have read through it and it 
generally looks good to me. One question though:

Section 3.3.4 says:
<quote>

    Once the state of each check list is Completed, and if the agent is
    the controlling agent, it nominates a candidate pair [RFC8445] and
    checks for each data stream whether the nominated pair matches the
    default candidate pair.  If there are one or more data streams with a
    match, and the peer did not indicate support for the 'ice2' ice-
    option, the controlling agent MUST generate a subsequent offer
    (Section 3.4.1), in which the connection address, port and transport
    protocol in the "c=" and "m=" lines associated with each data stream
    match the corresponding local information of the nominated pair for
    that data stream.
</quote>

In the second sentence, shouldn't it rather be if there is a line with a 
mismatch instead of a match ?

Thanks

-- Flemming
