Do you have an exhaustive list? Off the top of my head I can think of
the record which contains a struct sockaddr.

No, I mean the format output by the audit daemon.

Sounds like this falls in to the 'easy to produce' category. We also
need to consider how this data is consumed. I'll take this opportunity
to suggest again that a binary format produced by the kernel would be no
worse than a hex encoded binary format, and a whole lot easier for the
audit daemon to mangle into something usable on the output side.
