The addition of provenance is one useful addition provided by this concept... especially if the document is being passed around from broker to broker and BES endpoint. For this provenance to be useful it needs to be trusted... how are you going to record who (really) changed thing... signing or something else? And how will you stop the document and change history growing ecessively...?
