This looks good, I think, but shouldn't it be a delta to the text
accepted for CR15 [1]? I believe that the result would be mostly the
same, but the wording about "messages on such a channel" and "outside
this usage" will probably have to be tweaked.  For example, in the case
of SOAP 1.2, there's deliberately no "channel" per se.
