/**
 * A MessageContextListener is registered on the AxisService.
 * When a ServiceContext is attached to the MessageContext, 
 * the attachServiceContextEvent is triggered.
 * When an Envelope is attached to the MessageContext, 
 * the attachEnvelopeEvent is triggered.
 * 
 * These two events occur at critical points in the message sending
 * or receiving.  An implementation of the MessageContextListener
 * may log information, set special properties or trigger events.
 * 
 * For example the JAXWS module uses a MessageContextListener to 
 * register a JAXBCustomBuilder on the envelope's StAXOMBuilder.
