Because the majority of people needing audit need syscall records for it to 
make any sense. The auxiliary records generally report on the object of the 
syscall. We still require information about who was doing something, what they 
were doing, and what the result was. 

Even if you just get the AVC's, you still don't know what happened. If you get 
a deny record, was it really denied? The system could have been in permissive 
mode and the syscall succeeded. You only get the real decision when you have 
syscall records.
