How about AUDIT_CONTAINER for the auxiliary record? The one that starts
the container, I don't have a strong opinion on. Could be
AUDIT_CONTAINER_INIT, AUDIT_CONTAINER_START, AUDIT_CONTAINERID,
AUDIT_CONTAINER_ID, or something else. The API call that sets the ID
for filtering could be AUDIT_CID or AUDIT_CONTID if that helps decide
what the initial event might be. Normally, it should match the field
being filtered.
