 * the JMS acknowledgement mode for the message delivery when bean-managed 
 * transaction demarcation is used.
 * Its values are <code>Auto_acknowledge</code> or <code>Dups_ok_acknowledge</code>.  
 * If this property is not specified, JMS auto acknowledge semantics are assumed.
 *
 * <li> <code>messageSelector</code>.  This property is used to specify
 * the JMS message selector to be used in determining which messages a
 * JMS message driven bean is to receive.
 *
 * <li> <code>destinationType</code>.  This property is used to specify
 * whether the message driven bean is intended to be used with a queue or
 * a topic.  The value must be either <code>javax.jms.Queue</code> or
 * <code>javax.jms.Topic</code>.
 *
 * <li> <code>subscriptionDurability</code>.  If the message driven bean is
 * intended to be used with a topic, this property may be used to indicate
 * whether a durable or non-durable subscription should be used.   The
 * value of this property must be either <code>Durable</code> or <code>NonDurable</code>
