Wu, I have copied this reply to the list, as it is of general interest. I will follow up on schedule with just you.

We need, I think, to retain the language around the characteristics (async, non-solicited, etc), but remove the Mode attribute. > If this is the case, I would suggest we could deal with this issue > at a later stage of the WS-E specs development, since there are or > will be proposals on the table on event delivery that propose new > semantics to the specs.

If we delay, we may run over the same ground and waste time. Also, it may be that when some use case for extensibility appears later a Mode parameter will not be the best way to go. Rather than assume Mode will work for a use case we don't yet have, let's get rid of Mode now and when that use case shows up, design an extension (possibly in eventing or another spec) that address that use case directly. > I would love to hear your use cases which keep the semantics of WS-E > but extend its usability. The first use case, which we have seen a lot of discussion on, is the one raised by 6432 and addressed by MakeConnection. Another approach to this same use case in outlined in WS-Notification using a mechanism known as PullPoint. An approach like this one would work without changing the semantics of eventing. In fact this might work using the OASIS spec and eventing together unmodified.
