| * <p>Enables JAXB unmarshalling of a root document containing optimized binary data formats.</p> |
| * |
| * <p>This API enables an efficient cooperative processing of optimized |
| * binary data formats between a JAXB 2.0 implementation and MIME-based package |
| * processor (MTOM/XOP and WS-I AP 1.0). JAXB unmarshals the body of a package, delegating the |
| * understanding of the packaging format being used to a MIME-based |
| * package processor that implements this abstract class.</p> |
| * |
| * <p>This abstract class identifies if a package requires XOP processing, {@link #isXOPPackage()} |
| * and provides retrieval of binary content stored as attachments by content-id.</p> |
| * |
| * <h2>Identifying the content-id, cid, to pass to {@code getAttachment*(String cid)}</h2> |
| * <ul> |
| * <li> |
| * For XOP processing, the infoset representation of the cid is described |
| * in step 2a in |
| * <a href="http://www.w3.org/TR/2005/REC-xop10-20050125/#interpreting_xop_packages">Section 3.2 Interpreting XOP Packages</a> |
| * </li> |
| * <li> |
| * For WS-I AP 1.0, the cid is identified as an element or attribute of |
| * type {@code ref:swaRef} specified in |
| * <a href="http://www.ws-i.org/Profiles/AttachmentsProfile-1.0-2004-08-24.html#Referencing_Attachments_from_the_SOAP_Envelope"> |
