Re: [ebxml-msg] FW: Informal input to ebMS

[Doug Bunting <db134722@iplanet.com>]

Jeff and Mike,

I have a couple of questions on the consensus items:

• "cid based start parameter in the MIME Content-Type header" does not sound at all legal according to the MIME specifications.  The start MIME parameter accepts a content identifier as its value (the part of a cid URI after the colon), not a URI.
• "Payloads are not canonicalized during the digital signing process" seems to head away from interoperability.  If any intermediate makes a relatively small change (say, modifying the character set) to a payload, the recipient will be unable to validate the signature.  Canonicalization serves a number of useful purposes such as reducing the impact of inconsequential changes.  (And, in most cases, XML comments are not consequential.)

I much appreciated the sequence diagrams.  I'm reminded of one of
the issues from the list because the diagrams once again point out an inability
to request the business response and MSH acknowledgement in the same (asynchronous)
message.  You can't create a derivative of (3b) putting the two "responses"
together without combining them with a synchronous reply.

Your thoughts?

thanx,

Hi Ian,

 Attached is some input based on the current/past DGI ebMS interops.

 Also, attached are some examples of sequence diagrams we have been
 building, we would be willing to expand on these for inclusion
 in the spec or in some type of implementation guide...

 Can you forward me the concall number for the meetings Thursday,
 I'd like to dial in if that is ok with you.

 Thanks !

 Have fun in Miami !
