Subject: RE: [ebxml-msg] What Next?

Title: RE: [ebxml-msg] What Next?
I'm unclear why encapsulation is necessary to encrypt entire messages, especially if a payload item is already encrypted. It seems SSL would provide sufficient encryption of an entire message, including MIME headers.
I could see using S/MIME of OpenPGP to digitally sign an entire message, but SSL should be sufficient for encryption purposes.
Am I missing something?

We need to consider Encapsulation again.  This has a number of potential uses:

        Encryption (encrypt the entire document including MIME headers)
        Forwarding/Multi-hop (especially with the identified problems with Signatures)
        Third-Party Processing (Intermediate Timestamps...)
        Chunking (sending extremely large files in pieces)

I am sure there will be others.

We used this concept in the UCC Interop test to do encryption and it worked
quite well.  See document attached.

        I hope you have all had a pleasant break over the last couple of
weeks.  As the title says what do we do next?  It is up to you, but here are
some ideas to start with.

1 - we MUST capture, answer and resolve any question and issues during the 3
month public review of version 2.0
2 - The IIC TC would like to produce a conformance test/suite/documentation
for version 2.0, they will obvious need help from us to do this.
3 - The Business interface layer has never been written - do we need it?
4 - A primer/introduction to the messaging service
5 - A document to describe the minimum implementation.  This may be linked
to the IIC TC point above.

Question: - Do we still have outstanding requirements that still need to be
addressed? i.e. a definable business need for them.

        Over to all of you for comments.
