/**
 * NormalContentEvent is generated to indicate that the
 * normal content of a service is being presented. This event will be
 * generated in two situations: 
 *
 * 
 * At the end of a successful service selection operation, this
 * event will be generated as long as all of the service components
 * being presented are part of the normal content of the service. The
 * generation of this event in this situation signals a change in
 * state of the service context from the presentation pending
 * state to the presenting state. If even one of the service
 * components being presented is alternative content (as defined in
 * AlternativeContentEvent) then that event will be
 * generated instead.
 * 
 *
 * 
 * During the presentation of a service, this event will be generated
 * if alternative content was being presented and all of that
 * alternative content is replaced by content which is a normal part
 * of the service.  An example of this is when an
 * end user completes a pay per view dialog the video
 * advertising a service is replaced by the service itself.
