 * it is still required to implement the {@link ActivationSpec ActivationSpec}
 * interface.
 * 
 * <p>The ActivationSpec JavaBean contains the configuration information pertaining
 * to inbound connectivity from an EIS instance. A resource adapter capable of
 * message delivery to message endpoints must provide a JavaBean class
 * implementing the {@link ActivationSpec ActivationSpec} interface which may be annotated
 * with the <code>Activation</code> annotation for each supported
 * endpoint message listener type.
 * 
 * <p>The ActivationSpec JavaBean has a set of configurable properties specific to
 * the messaging style and the message provider.
 * 
 * <p>Together with the messageListener annotation element, this annotation
 * specifies information about a specific message listener type supported by the
 * messaging resource adapter.
