A message containing a second body part at the TOP level identified with
application/vnd.eb+xml would be in violation of the ebXML TR&P packaging spec. A
valid ebXML message MUST contain only ONE ebXML header document at the top
level.

Of course it is perfectly legal to have a payload body part of type
multipart/related that contains a application/vnd.eb+xml body part (essentially
an encapsulated ebXML message within an ebXML message).
