I suspect Steve is mixing up AUDIT_CONTAINER_OP with AUDIT_CONTAINER_ID,
confusing the fact that they are two seperate records. As a summary,
the suggested records are:
CONTAINER_OP audit container identifier creation
CONTAINER audit container identifier aux record to an event
and what Paul is suggesting (which is fine by me) is:
CONTAINER_OP audit container identifier creation event
CONTAINER_ID audit container identifier aux record to an event
Steve, please indicate you are fine with this.
