Ooops, somewhat clashing with my proposal at

I forgot about the case where WSDL wants to specify that the body will
be empty. So now we have three scenarios:

1) empty body
2) body containing a single element according to a given schema element
3) body containing anything at all

we could add

4) body containing data according to a given schema type definition

and that would subsume both 1 and 3. But in fact we've decided before to
only keep element="..." and to drop type="...". Do we special-case
scenarios 1 and/or 3 or do we revisit the decision on scenario 4?
