Not exactly. There is a listing of every event type in the headers as well as 
when you just type "ausearch -m". But what's in each record is not in a 
released document right now.

The interpretation of that field can be found in the audit parsing spec:

It is a gentleman's agreement. I have personally reviewed and fixed all audit 
messages to make sure they are uniform except the selinux avcs. Anytime I 
suggest normalizing them, they get upset and say it will break existing 
tools. So, I have no way of making avcs follow a schema unless they want to 
change it. As for userspace, I enforce the gentlemen's agreement by the 
logging functions in libaudit.

All that's required in an audit event is: Date and time of event, type of 
event, user associated with the event, subject identity, resources involved. 
outcome, Sensitivity labels of subjects and objects. Anything else is icing 
on the cake.
