The record is not created by auparse. The kernel sends this whenever there is 
a multipart event. This record is stripped before putting the event to disk to 
save disk space. We can get along with this because it can be deduced later 
and running reports from disk is not realtime. On the realtime interface it is 
passed along so that recognizing that an event is complete can occur 
immediately upon receipt. Realtime event processing kind of needs this 
guarantee.
