 /**
 26  
  * Annotation used to <em>define</em> new managed beans, including limited/lightweight
 27  
  * initialization. For complex initialiation, the XML specification is necessary.
 28  
  * <p>
 29  
  * One of the advantages is that, on the XML side, it is always necessary to provide complete class
 30  
  * names; here on the Java/annotation side, we can leverage imports.
 31  
  * <p>
 32  
  * The managed bean will have a name that matches the property name; this allows such a bean to be
 33  
  * referenced via the "bean:" binding prefix, or via
 34  
  * {@link org.apache.tapestry.IComponent#getBeans()}.
 35  
  * <p>
 36  
  * This annotation adds a new {@link org.apache.tapestry.spec.IBeanSpecification} to the
 37  
  * {@link org.apache.tapestry.spec.IComponentSpecification}.
