Subject: Proposal for extended PullRequest


 Based on todays's discussion:
Here are some samples of extended PullRequest, followed by the proposed (rough) schema.
I believe this is still backward compatible, Pim? (PullRequest allows for a sequence of any as children elements)
 
Semantics:
 
The MSH receiving such a PullReques MUST either:
(a) return a message assigned to the same @mpc, and that has same eb:RefToMessageId value as @reftomessageid (if the latter is specified) and same eb:ConversationId value as @conversationid (if  the latter is specified) and that contains the message properties specified as children of <eb:Select> (if any).
(b) return error EBMS:0006 (EmptyMessagePartitionChannel ) if no message is currently assigned to this MPC , that matches the selecting conditions in (a).
 
Examples:
 
<eb:SignalMessage>
  <eb:MessageInfo>
    <eb:Timestamp>2006-07-25T12:19:05</eb:Timestamp>
    <eb:MessageId>UUID-2@initiator.example.com</eb:MessageId>
  </eb:MessageInfo>
  <eb:PullRequest mpc="http://msh.example.com/mpc123">
    <eb:Select reftomessageid="1234"/>
  </eb:PullRequest>
</eb:SignalMessage>
