/**
 * {@link XmlAdapter} that binds the value as a SOAP attachment.
 *
 * 
 * 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.
 *
 * 
 * the model builder code and the code generator does the conversion and
 * shield the rest of the RI from this mess.
