/**
* <p>Composite object XML mappings represent a relationship between two classes. In XML, the "owned"
* class may be nested with the element tag representing the "owning" class. This mapping is, by
* definition, privately owned.
*
* <p><b>Composite object XML mappings can be used in the following scenarios</b>:<ul>
* <li> Mapping into the Parent Record </li>
* <li> Mapping to an Element </li>
* <li> Mapping to Different Elements by Element Name </li>
* <li> Mapping to Different Elements by Element Position </li>
* </ul>
*
* <p><b>Setting the XPath</b>: TopLink XML mappings make use of XPath statements to find the relevant
* data in an XML document. The XPath statement is relative to the context node specified in the descriptor.
* The XPath may contain path and positional information; the last node in the XPath forms the local
* root node for the composite object. The XPath is specified on the mapping using the <code>setXPath</code>
* method.
*
* <p>The following XPath statements may be used to specify the location of XML data relating to an object's
* name attribute:
*
* <p><table border="1">
* <tr>
* <th id="c1" align="left">XPath</th>
* <th id="c2" align="left">Description</th>
* </tr>
* <tr>
* <td headers="c1">.</td>
* <td headers="c2">Indicates "self".</td>
* </tr>
* <tr>
* <td headers="c1">phone-number</td>
* <td headers="c2">The phone-number information is stored in the phone-number element.</td>
* </tr>
* <tr>
* <td headers="c1" nowrap="true">contact-info/phone-number</td>
* <td headers="c2">The XPath statement may be used to specify any valid path.</td>
* </tr>
* <tr>
* <td headers="c1">phone-number[2]</td>
* <td headers="c2">The XPath statement may contain positional information. In this case the phone-number
* information is stored in the second occurrence of the phone-number element.</td>
* </tr>
* </table>
*
* <p><b>Mapping into the Parent Record</b>: The composite object may be mapped into the parent
* record in a corresponding XML document.
