>>1. Message Id - a unique id for a message
>>2. RefToMessage Id - a way of identifying an earlier message to which this

>>4. Creation Time - the time a message was initially created
>>5. Expiry Time - the time after which the recipient of a SOAP message should

mm1: I believe, if only informally, this discussion has occurred in 
XMLP.  Dave, can you please re-address this with XMLP and let us 
concentrate on what is our primary objective? Thanks.
