Hi: Dominic： Thank you very much for your thoughtful comments. I'll just address the first one. For the rest, please give me some time.
ad "New EPR or re-write the current WS-AG document?" during the renegotiation the agreement is in some kind of intermediate change (i.e. it might be in a proposed new status that is not yet accepted by the other party), don't we need a new EPR for that?
The reason that I wanted to re-write the current WS-AG rather than a new EPR was that one could never know who might be using the old EPR. In a complex scenario like the one I mentioned in Business Grid Computing case or some broker case, old EPR might be propagated to other parties who would be using it. So I thought that it would not be realistic to assure that the NEW EPR would be propagated to all the bodies who might be referring to the old EPR. On the other hand, re-writing the current WS-AG document kept by the Agreement Responder does cause a serious race condition when the AR is the requestor for modifying the Agreement. (ie. it must be re-written only after the AI says he agrees, but when?)
What would the ResourceProperties (e.g. the SDTs or GTs) look like in the intermediate state? (DB, 2007/08/22) I am assuming that the service (under the old SLA) is still being provided even while the renegotiation is going on. (If the service is stopped, then we don't need renegotiation. We just terminate the old agreement and create a new agreement)
As for the rest of your comments, essentially I agree with you. The only problemis that some of them seem to be very difficult to address :-( In any case, please give me some time as I can only do this work sporadically.

Hi Toshi,
I did some brainstorming and added some random comments/wishes/ideas. Please have a look whether anything could be useful for the further proceeding. I don't know how much you have discussed and discarded before. Please feel free to ask me, in case my comments are confusing.
Best regards,
Dominic
