In my mind Sanjiva's proposal is a good idea. However, I wonder if this new model of events producer/consumer/filter/transport/security should not be captured in a separate specification before making any changes to WSDL. I believe that some work has already been done by the Internet community in that space a long time ago. We could re-use this to come up with a new spec. (say WS-Event) defining events in a WS world and proposed some WSDL changes if necessary.
