Subject: Re: [emergency] BEA, Microsoft, and Tibco Release WS-EventingSpecification

Thanks, John,

This is of more than a little interest. It troubles me. I don't 
understand what this is good for in and of itself. It doesn't "DO" 
anything but pass messages as far as I can see, and doesn't do 
anything else that isn't already possible.  Also it introduces yet 
more new "notation" that uses "?"., "*" and "+" for cardinality 
values. WSRP already has a registry-based WSDL mechanism for the 
processes described in this specification, not to mention a whole 
flock of mechanisms that were crafted in order to leave room for 
"true" eventing. Eventing requires (IMHO) "triggering" mechanisms 
with clear defined results quite beyond receipt of a simple message 
whether it is an event, notification or what? and regardless of 
whether or not any such "subscription" is involved beyond 

It also bothers me when I see a specification that so concerned with 
fault messages and failure scenarios.

All of which adds up in my mind to an attempt to somehow "own" the 
term "eventing" and apply the concept of "subscription" to it.

I think we can do a lot better.
