Of course, we always have to have multiple versions of a spec

In my recent posting which referenced the announcement of the W3C "Member Submission" of WS-Addressing, I forgot to mention that this is the 2nd of such submissions that have recently occurred. On April 26, 2004, another addressing specification, WS-MessageDelivery, was submitted to the W3C as a "Member Submission". Both WS-MessageDelivery and WS-Addressing "address" the same issues, which is how to specify metadata in an XML message that describes endpoints or destinations. Information such as From, To, ReplyTo, and FaultTo are specified.

Now that both specifications are submitted to the W3C, one can only hope that the submitting companies will work together through the W3C Working Group process and come to some convergence. I hear rumors (or perhaps I'm starting one) that the recent submitters wish to fast-track the current spec through the process, yet also plan to use the previous WS-MD spec as input. That's all good news if you ask me.
