This sounds too strong
Something like the following (with wordsmithing required)
" An ack means that the acknowledged message has satisfied all the
ws-reliabiliy requirements placed on it for delivery, and the receiving
user has accepted the responsibility for completion of delivery, using
the mechanism specified in its contract with the Receiving Reliable
message processor.."
<JD> Tom: I don't think the statement was too strong, if you read carefully the above
definition of "delivery", which is nothing more than a transfer of *responsibility*
to the next layer or processor - which is in fact aligned with what you propose.
So "delivery" does not mean here the actual transfer of the message to its final
destination/user, in which case I would agree with you.
However, I take it that my def could be confusing.
How about a more explicit def taking the best of your comments, but restating
the definition of "delivery" above:
"An acknowledgement means that the acknowledged message has been
successfully delivered, meaning simply that it has satisfied all the
reliability requirements placed on it for delivery, and that the RMP
having made the message available to its next processor, is no longer
responsible for processing it further."
Note that we don't need any mention of "users", and even more of "acceptance".

Jacques
