Thank you and I am glad that a task force is looking into this. I'll follow
their proceedings.

WSDL 1.2 message patterns currently make fewer commitments than a SOAP
1.2 message >exchange< pattern. For instance, you may wish to compare
the following discussion of message >exchange< patterns


with the introductory text of WSDL 1.2 Part 2


If you find this issue subtle, you're in good company. A task force
within the Web Service Description working group has been working to
clarify the issues.

We chose a different name because there were differences.

There is no intention to do so currently, but that may change pending
the investigation by the task force mentioned above.

Thanks for writing!
