Business (Legal) analysis of ebMS 3.0

Hi,

Im doing an analysis of some protocols from a business (and legal) 
requirements point of view. ebMS is one of analysed protocols. One area 
of concern is Acknowledge of Receipt funcitonality and rules of 
evidence. Looking at the older may 3.0 draft it seems as if ebMS 
proposes, for some patterns, acknowledgements 5+1+1 times which seems to 
be rather many.

Could someone pointme to the latest ebMS spec so I have the latest info 
available?

I would also appreciate if a clarification could be given if  ebMS 
includes the ebMS Acknowledge (intermadiary and party) found in ebMS 2.0?

thanks
