    [Name]:      TSubConnNotification
    [Semantics]: Sent by a subconnection provider to its control clients raising a CSubConNotificationEvent.
    			 The message has to be consumed as the CSubConNotificationEvent is refcounted. I.e.: the
    			 refcount is increased with each post and hence its dispatch has to consume the message
    		     by calling iRefCountOwnedSubConNotification.Close() (decrease the refcount).

    [Type]:      Notification

    [Structure]:
    param:       iRefCountOwnedNotification - refcounting wrapper that holds a reference to the
    			 XPlaneEvent.
