The statement in [1] "The methods described here treat the multipart MIME structure as essentially a part of the transfer protocol binding, i.e., on par with the transfer protocol headers as far as the SOAP message is concerned. " So, how about adding the following new DR6xx in section 3.6 to address normative XP processing: [DR6xx] Arbitrary content (to include binary data) outside the XP message shall be accomodated by the protocol binding.
