Yeah, the current spec is broke and/or misleading in how it talks about
other headers.

I see no reason to have different ID's in the ebXMLHEader document and
the MIME bodypart header.  I cannot see a reason for the MIME bodypart
to duplicate what's in the bodypart text.  What part of an MSH would
split up the bodyparts (ebxmlheader and payload) and then need to tie
them back together?

(This is different from the Content-ID in the payload, of course, since
we place no constraints on the payload, but do have the requirement that
the ebxmlHeader document be able to refer to the payload.)

Now, having said all that, if someone can really explain that they need
a Content-ID header in the ebxmlheader MIME headers, then I'd add
	The Content-ID, if present, MUST have the same value as the documetn ID
in the ebXMLHeader document.
