Re: [wsrm] Issue: ordering and missing message behavior
My feeling is that (a) is better. Though the protocol is named WSRM, 
there is still chance that the message fail to delivered successfully. 
In that case, application level retry mechanism might be employed. 
Therefore, the application might receive the missing messages 
eventually. In this case, the application can take less care about 
message ordering if it will *not* see any messages not in order.

Comment?

Cheers, -Patrick
