Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from [[#GetEventHandle]] to check whether a message is available, then if so it uses [[#ReceiveMessage]]. The actual handling for message IDs is done in the app itself(see [[#NotificationMessage]]).
