Again, I think I've seen INFOs and/or BYEs carrying ISUP informatio in multipart, without any other body (unfortunately I have to use the word "think", because I don't have any real examples in front of me :) But, I have nothing against saying that one SHOULD NOT (or even MUST NOT) SEND it. But, I do think one should be prepared to RECEIVE such messages, in order to be backward compatible with existing implementations which may not be fully compliant the draft. And, regarding Dan's example: if a client is not able to handle multipart carrying only SDP, I don't think it will be able to handle a multipart carrying SDP and something else either - and we will have the problem Francois presented earlier (the multipart, and the SDP innit, is thrown away).
