40 * {@link XmlAdapter} that binds the value as a SOAP attachment.
41 *
42 * <p>
43 * On the user classes the SwA handling is done by using the {@link XmlAttachmentRef}
44 * annotation, but internally we treat it as a {@link XmlJavaTypeAdapter} with this
45 * adapter class. This is true with both XJC and the runtime.
46 *
47 * <p>
48 * the model builder code and the code generator does the conversion and
49 * shield the rest of the RI from this mess.
