Problems consuming a web service in ABAP

Question

We wish to consume an external web service from ABAP but the provided WSDL file contains syntax not supported by SAP - namely "mixed content".  A response from Roman Glushkov      in forum thread [Call Sharepoint Web Service; seemed to offer a solution. 
The WSDL file was edited as suggested by Roman and the Service Consumer proxy was successfully created from this edited version.  However, in our SAP release (Basis release 700 support pack SAPKB70018) the "untyped mapping" indicator is not shown anywhere so we are unable to set that for those elements that were set edited in the WSDL.
The problem now is that when calling a method where the return parameters include one of these edited elements we get the error "SOAP:1,001 CX_ST_MATCH_TYPE:XSLT exception.System expected a value for the type g" presumably because SAP is trying to de-serialise the response rather than just return the data as an XML string.
Does anyone know how to get this "untyped mapping" indicator or can anyone suggest another way to solve this mixed content issue?
TIA

Hi Tim
I've sort of got further in that I I can now call the web service method without error but structure returned is empty even though I know the SOAP response has data. 
What I did was to go back to the WSDL and re-write the type declaration bit to fully describe the response message.
The appropriate portion of the original WSDL was;
      <s:element name="getActionListResponse">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="getActionListResult">
              <s:complexType mixed="true">
                <s:sequence>
                  <s:any />
                </s:sequence>
              </s:complexType>
            </s:element>
          </s:sequence>
        </s:complexType>
      </s:element>
The response SOAP message was;
<getActionListResponse xmlns="http://webcominc.com/">
     <getActionListResult>
          <RESULT xmlns="">
               <RESULT>
                    OK
               </RESULT>
               <REASON />
               <ACTION>
                    View
               </ACTION>
               <ACTION>
                    Change Status
               </ACTION>
          </RESULT>
     </getActionListResult>
</getActionListResponse>
So I re-wrote the WSDL as follows;
<s:element name="getActionListResponse">
   <s:complexType>
      <s:sequence>       
         <s:element minOccurs="0" maxOccurs="1" name="getActionListResult">
             <s:complexType>
               <s:sequence>
                  <s:element minOccurs="0" maxOccurs="1" name="RESULT">
                     <s:complexType>
                        <s:sequence>
                           <s:element name="RESULT" type="s:string" minOccurs="1" maxOccurs="1" />
                           <s:element name="REASON" type="s:string" minOccurs="1" maxOccurs="1" />
                           <s:element maxOccurs="unbounded" name="ACTION" type="s:string" minOccurs="0" />
                        </s:sequence>
                     </s:complexType>
                  </s:element>
               </s:sequence>
            </s:complexType>
         </s:element>
      </s:sequence>
   </s:complexType>
</s:element>
Using this new version of the WSDL I recreated the ABAP Proxy but as I said this now returns an ABAP structure that is empty.  I'm new to WSDL so its very probable that my attempt at defining the response message is incorrect or maybe it is something to do with the fact that the response message has two elements called RESULT - one being the child of the other?
