Openshift Logging documentation needs definition of log types.

The logging documentation talks about 3 categories of logs: audit, infrastructure and application; but it does not seem to have a clear definition of which logs are included in each category (or it it does, its not easy to find)

Users should be able to answer questions like this: Do you know whether OVN-Kubernetes network policy events (https://docs.openshift.com/container-platform/4.9/networking/network_policy/logging-network-policy.html) fall into the audit category?
