specifying a type for use=literal messages is not supported.

[clivefoley]

Does anyone know how to fix the error in the subject line? I am trying
to Add a web reference to a web service and this error occurs.

This is the binding for the web service :

<wsdl:binding name="bpelProcessSoap" type="tns:startProcessPortSoap">
<soap:binding style="document"
transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdlperation name="addLeadToProcess">
<soapperation soapAction="" style="document"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdlutput>
<soap:body use="literal"/>
</wsdlutput>
</wsdlperation>
</wsdl:binding>
