Question about WSDL & MIME

[Douglas Bitting]

OK, so this doesn't directly relate to Axis, but indirectly it does... I'm trying to 
figure out what the WSDL should look like when dealing with MIME
data (i.e., SOAP w/ Attachments).

Let's say I have a method that I expose as a service.  The method signature is "public 
DataHandler getData()"  Does the WSDL look something like the
following (various bits ommitted for brevity)

...
<wsdl:message name="getDataRequest"/>
<wsdl:message name="getDataResponse">
  <wsdl:part name="return" type="tns1:DataHandler"/>
</wsdl:message>
...
<wsdl:binding ...>
  <wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
  <wsdl:operation name="getData">
    <wsdlsoap:operation soapAction="..."/>
    <wsdl:input name="getDataRequest">
      <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                     namespace="..." use="encoded"/>
    <wsdl:input>
    <wsdl:output name="getDataResponse">
      <wsdlmime:multipartRelated>
        <wsdlmime:part>
          <wsdlsoap:body parts="" use="encoded"/>
        </wsdlmime:part>
        <wsdlmime:part>
          <wsdlmime:content part="return" type="application/octet-stream"/>
        </wsdlmime:part>
      </wsdlmime:multipartRelated>
    </wsdl:output>
  </wsdl:operation>
</wsdl:binding>
...

The main thing I'm confused about is whether the <wsdlsoap:body .../> is needed in the 
output portion.  As near as I can tell, the above would be
compliant with the WSDL 1.1 spec, as well as the JAX-RPC spec.  Am I close on this?  
Should I be pestering a different mailing list?  :-)

Cheers,
