Include mapped output as the value of another output (needed for SAGE X3 integration)

We are trying to integrate with Sage X3 services using OIC.  Sage services use SOAP messages that include a JSON object in an XML element.  For example:

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:xsd="http://www.w3.org/2001/XMLSchema&quot; xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/&quot; xmlns:wss="http://www.adonix.com/WSS"&gt;
   <soapenv:Header/>
   <soapenv:Body>
      <wss:save soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"&gt;
         <callContext xsi:type="wss:CAdxCallContext">
            <codeLang xsi:type="xsd:string">ENG</codeLang>
