Hopefully you've found the following question to be answered by
my previous post on risk-related events:

Now, about table lookup of request and message event indices:

This is on our roadmap as part of the next major functional area,
versioning.  The shim will use the ApiLevel variable to determine
request and message formats, check the event indices against the
database, and complain/exit if there are differences.  Downstream
users would then be free to read from the same tables to learn
about the supported events for any given level of the api.

As for other uses for such tables, say as documentation:

Hah!.  Dream on.  You'll find you're better off with the sample
client sources, which I hope you'll obtain.  As Russ points out,
the /event/event index/api level/possibly attribute descriptor
or type tag/ tables will encode a number of levels of detail:

All too true.
