Hi Karen,

section 3 should describe what currently is standardized. Am I right that there 
is no RFC on CMT SCTP (yet)… and that this was/is the reason that there was 
some discussion that this is out of scope? If so, what the status of CMT SCTP? 
Will there be potentially be an RFC anytime soon?

However, in section 3 if there are any similarities to MPTCP in SCTP, either in 
MH or CMT, these could be described in a similar way and potentially even refer 
to MPTCP or the other way around. If SCTP is described independent of MPTCP 
that’s fine as well, or potentially even better for the start. As soon as we 
then start writing section 4, we anyway to have to detect those similarities 
and can still add references or adapt the wording to use the same term later on.
