How can I unmarshal and handle a SOAP fault in Camel?

Issue

In Camel, how can I catch a SOAP fault and inspect the fault to determine how to handle the error? For instance, if I receive a SOAP fault with the following format, how would I handle the fault and also examine the message's returned FAIL code ?

    <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
       <soap:Body>
          <soap:Fault>
             <faultcode>soap:Server</faultcode>
             <faultstring>an expected failure occurred</faultstring>
             <detail>
                <ns2:MessageException xmlns:ns2="http://message.ws.mycxf.examples.redhat.com/">
                   <code>FAIL</code>
                </ns2:MessageException>
             </detail>
          </soap:Fault>
       </soap:Body>
    </soap:Envelope>
