RE: [ebxml-msg] [Fwd: Some AS4 queries]

Hi Timothy

We had some queries we hoped you could help provide some clarity on or atleast poing to someone who can help. 


- The spec states that Signal Msg cannot have body. How is bundled msg handled ? Is it thru attachments ? Or does this constraint apply to a pure Signal Message ?


- If a msg has to be retried, then is it necessary to again bundle the same user msg, errors etc as original ? 

- Does the MSH implementation need to wait for the actual backend service to initiate a pull to the MSH or can it send the pull signal message on its own based on some agreements ?

- How is the identity of the sender determined from a signal message. From the WSS credentials ?

- Msg delivery : In a bundled msg, should we assume that an eb:Receipt for a UserMsg means that even the errors/receipts are delivered ? Similarly if the MSH returns error that the User Msg is not delivered, then is the error also not delivered ?

- Is there a One-One correspondence with User Msg Headers and the number of attachments or can there be more attachments than the headers.

- Can there be multiple payloads for a User Msg Header ? What I wanted to know is how can partners send multiple messages in one User Msg e.g. can multiple quotes be sent as one user message ?

- The ebMS speaks about a PullAndPull MEP. Does AS4 support this ?

- Finally can we have some more sample messages covering some of these scenarios ? So we know how they look on the wire.

Appreciate any help you can provide..

Thanks
