/**
* {@link XmlAdapter} that binds the value as a SOAP attachment.
*
* <p>
* On the user classes the SwA handling is done by using the {@link XmlAttachmentRef}
* annotation, but internally we treat it as a {@link XmlJavaTypeAdapter} with this
* adapter class. This is true with both XJC and the runtime.
*
* <p>
* the model builder code and the code generator does the conversion and
* shield the rest of the RI from this mess.
