     * <li>org.omg.CORBA_2_3.ORB</li>
     * <li>any other connection factory defined by a resource adapter</li>
     * </ul>
     *
     * If web.xml contains a resource-ref with injection targets, all resource-ref entries
     * of the same name are ignored in web fragments. If web.xml does not contain any
     * injection-targets, then they are merged from all the fragments.
     * If web.xml does not contain a resource-ref element of same name, but 2 fragments
     * declare the same name it is an error.
     * resource-ref entries are ONLY for connection factories
     * the resource-ref says how the app will reference the jndi lookup relative
     * to java:comp/env, but it is up to the deployer to map this reference to
     * a real resource in the environment. At the moment, we insist that the
     * jetty.xml file name of the resource has to be exactly the same as the
     * name in web.xml deployment descriptor, but it shouldn't have to be
     * 
     * <p>
     * Maintenance update 3.0a to spec:
     * <p>
     *   Update Section 8.2.3.h.ii with the following -  If a resource reference
     *   element is specified in two fragments, while absent from the main web.xml,
     *   and all the attributes and child elements of the resource reference element
     *   are identical, the resource reference will be merged  into the main web.xml.
     *   It is considered an error if a resource reference element has the same name
     *   specified in two fragments, while absent from the main web.xml and the attributes
     *   and child elements are not identical in the two fragments. For example, if two
     *   web fragments declare a <code>&lt;resource-ref&gt;</code> with the same <code>&lt;resource-ref-name&gt;</code> element
     *   but the type in one is specified as javax.sql.DataSource while the type in the
     *   other is that of a java mail resource, then an error must be reported and the
     *   application MUST fail to deploy.
