How to implement/modify SOAP with Attachments/MTOM in FSW

Issue

• The quickstart for SOAP with Attachments (SwA) puts the attachment reference directly in the body. In the soap-attachment quickstart SoapAttachmentClient receives the following SOAP response from the SwitchYard endpoint:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
    <env:Header xmlns:env="http://www.w3.org/2003/05/soap-envelope"/>
    <soap:Body>
        <ns2:echoImageResponse xmlns:ns2="urn:switchyard-quickstart:soap-attachment:1.0">cid:external-switchyard.png</ns2:echoImageResponse>
    </soap:Body>
</soap:Envelope>

• I would be very happy if you can provide a working example of the quickstart that responds with:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
    <env:Header xmlns:env="http://www.w3.org/2003/05/soap-envelope"/>
    <soap:Body>
        <ns2:echoImageResponse xmlns:ns2="urn:switchyard-quickstart:soap-attachment:1.0">
            <attachments>
                <attachmentName>external-switchyard.png</attachmentName>
                <attachmentContent>cid:external-switchyard.png</attachmentContent>
            </attachments>
        </ns2:echoImageResponse>
    </soap:Body>
</soap:Envelope>

• Can you edit it so it also returns the attachment name in the body? I can then try to update our code based on the example.
• We also want to use JAX-WS and MTOM&XOP. In our non-SwitchYard interfaces MTOM has worked without much effort and the SOAP content looks something like:

<attachments>
  <attachment>
    <fileName>order_000000000000000.csv</fileName>
    <attachmentData>
      <xop:Include href='cid:attachmentData-e992f924-9876-44bd-a245-bcd19e9506eb@ws.jboss.org' xmlns:xop='http://www.w3.org/2004/08/xop/include'/>
    </attachmentData>
  </attachment>
</attachments>

• But if trying it like in the soap-attachment quickstart, it looks like this:

<attachments>
    <attachmentName>order_000000000000000.csv</attachmentName>
    <attachmentContent>cid:order_000000000000000.csv</attachmentContent>
</attachments>

• How do we get that behavior with SwitchYard/Camel?
