After thinking a little more, it seems to me this would be a useful
addition.

Usecase: A response message could optionally return one or more
"attachments".

We do have an example of having attachments in the MIME binding section
of the specification (Section 5.11 Example 7) but, there is no way to
specify those as optional with variable cardinality (minoccurs,
maxoccurs). The example claims these are optional in the description
part but, neither the "message" definitions (A 4.1 WSDL schema) nor the
MIME bindings ( 4.4 MIME binding Schema) permit this.

Regards, Prasad
