21   * Use this BeanDefinitionParser when you need a "wrapper" element for an ObjectFactory.
22   * For example, suppose we have the following class:
23   * 
24   *   class Car
25   *   {
26   *     private ObjectFactory<Wheel> wheel;
27   *   }
28   * 
29   * The following registration in the namespace:
30   *
31   *   registerBeanDefinitionParser("wheel", new ObjectFactoryWrapper("wheel"));
32   * 
33   * would allow a config such as:
34   * 
35   *   <car>
36   *     <wheel>
37   *       <prototype-object class="com.wheelsrus.BigWheel">
38   *         <properties>
39   *           <spring:property name="tire" value="goodyear"/>
40   *           <spring:property name="diameter" value="35R"/>
41   *         </properties>
42   *       </prototype-object>
43   *     </wheel>
44   *   </car>
