Using WSDL to Indicate WS-A Headers

Question

I'm implementing a SOAP-based web-service and have got WS-Addressing working. However, I can't see how to get the WSDL to publish what the client should use as the value of the wsa:To element.

I have used the snippet below in my WSDL, and used SOAP-UI to generate a request. It seems that SOAP-UI recognises that wsa:action should be set to "http://myco.com/myOperation", although it doesn't add this header automatically. I have to select the "Add WS-A Headers" menu option.

My problem is that it doesn't add a wsa:To header. Can anyone tell me how I amend my WSDL to tell clients that a wsa:To is required and that its value should be "http://myco.com/cap/services/v1"?

Thanks

<wsdl:portType name="MyPortType">
    <wsdl:operation name="MyOperation">
        <wsdl:input message="tns:MyRequestMessage" name="Request"
                    wsaw:Action="http://myco.com/myOperation"/>
        <wsdl:output message="tns:MyResponseMessage" name="Response"/>
    </wsdl:operation>
</wsdl:portType>

<wsdl:binding name="MyBinding" type="tns:MyPortType">

    <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsaw:UsingAddressing wsdl:required="true"/>
    <wsdl:operation name="MyOperation">
        <soap:operation soapAction="" style="document"/>
        <wsdl:input>
            <soap:body use="literal"/>
        </wsdl:input>
        <wsdl:output>
            <soap:body use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>


<wsdl:service name="MyService">
    <wsdl:port binding="tns:MyBinding" name="MyPort">
        <soap:address location="http://myco.com/services"/>
        <wsa:Address>http://myco.com/cap/services/v1</wsa:Address>
    </wsdl:port>
</wsdl:service>

To achieve this I defined the namespace for ws addressing 2005 version

<xs:schema ... xmlns:wsa5="http://www.w3.org/2005/08/addressing">
 ....
</xs:schema>

a message type

<wsdl:message name="wsaHeader">
        <wsdl:part name="MessageID" element="wsa5:MessageID" />
        <wsdl:part name="RelatesTo" element="wsa5:RelatesTo" />
        <wsdl:part name="From" element="wsa5:From" />
        <wsdl:part name="ReplyTo" element="wsa5:ReplyTo" />
        <wsdl:part name="FaultTo" element="wsa5:FaultTo" />
        <wsdl:part name="To" element="wsa5:To" />
        <wsdl:part name="Action" element="wsa5:Action" />
</wsdl:message>

Then in my input and output I placed the following tags.

<wsdl:input>
    <soap:header use="literal" message="tns:wsaHeader" part="Action"/>
    <soap:header use="literal" message="tns:wsaHeader" part="To"/>
    <soap:header use="literal" message="tns:wsaHeader" part="FaultTo"/>
    <soap:header use="literal" message="tns:wsaHeader" part="ReplyTo"/>
    <soap:header use="literal" message="tns:wsaHeader" part="From"/>
    <soap:header use="literal" message="tns:wsaHeader" part="RelatesTo"/>
    <soap:header use="literal" message="tns:wsaHeader" part="MessageID"/>
    <soap:body use="literal" />
  </wsdl:input>
  <wsdl:output>
    <soap:header use="literal" message="tns:wsaHeader" part="Action"/>
    <soap:header use="literal" message="tns:wsaHeader" part="To"/>
    <soap:header use="literal" message="tns:wsaHeader" part="FaultTo"/>
    <soap:header use="literal" message="tns:wsaHeader" part="ReplyTo"/>
    <soap:header use="literal" message="tns:wsaHeader" part="From"/>
    <soap:header use="literal" message="tns:wsaHeader" part="RelatesTo"/>
    <soap:header use="literal" message="tns:wsaHeader" part="MessageID"/>
    <soap:body use="literal" />
  </wsdl:output> 

You may only need to add the To tag for your purposes.
