Unique message element QNames is a reasonable way to ensure that a
service can dispatch a message to the right operation.  But as I
understand it, such a mechanism would not satisfy the OperationName
feature, which would require extra (and unnecessary in this case) goo to
be squirted into the message.

I agree that a service needs to be able to know what to do with any
particular message.  That's built into my assumption about how to build
any Web service.  But constraining the solution to this problem to the
particular strategy of inserting the Operation Name into the message
doesn't seem right.

In any case, if functionality is always "required", there doesn't seem
to be much point in giving it a feature URI that can appear in the
markup and will appear in the component model, instead of just using
text in the spec.
