/**
 * <p>Used to enable JNDI dependency injection.</p>
 *
 * <p>A member can be injected with an object from the JNDI tree if a 
 * {@code NamingContext} is available for the specified member. Such a 
 * {@code NamingContext} can be defined at package-, class- or at member-level. 
 * There are two more requirements for members to support JNDI injection:
 * <ul>
 * <li>Members must be marked with the {@code Inject} annotation.
 * <li>Members, for which a {@code NamingContext} is made available at package- 
 * or class-level, must enable wiring {@code BY_NAME} or wiring {@code BY_TYPE} 
 * through the {@code Wiring} annotation. Members that are marked with the
 * {@code NamingContext} support wiring {@code BY_NAME} and {@code BY_TYPE} by 
 * default.
 * </ul></p>
 * 
 * <p>Members marked with this annotation MUST also be annoted with 
 * {@code Inject}, otherwise the beanlet definition fails.</p>
