 * 
 * 	
 * 
 * 	  The persistence-context-ref element contains a declaration
 * 	  of Deployment Component's reference to a persistence context
 * 	  associated within a Deployment Component's
 * 	  environment. It consists of:
 * 
 * 		  - an optional description
 * 		  - the persistence context reference name
 * 		  - an optional persistence unit name.  If not specified,
 *                     the default persistence unit is assumed.
 * 		  - an optional specification as to whether
 * 		    the persistence context type is Transaction or
 * 		    Extended.  If not specified, Transaction is assumed.
 *                   - an optional list of persistence properties
 * 		  - optional injection targets
 * 
 * 	  Examples:
 * 
 *             &lt;persistence-context-ref&gt;
 *               &lt;persistence-context-ref-name&gt;myPersistenceContext
 *               &lt;/persistence-context-ref-name&gt;
 *             &lt;/persistence-context-ref&gt;
 * 
 *             &lt;persistence-context-ref&gt;
 *               &lt;persistence-context-ref-name&gt;myPersistenceContext
 *                 &lt;/persistence-context-ref-name&gt;
 *               &lt;persistence-unit-name&gt;PersistenceUnit1
 *                 &lt;/persistence-unit-name&gt;
 *               &lt;persistence-context-type&gt;Extended&lt;/persistence-context-type&gt;
