A question about "level". Is the intention that the value can be anything, e.g. some new event next month might use the values "1", "2, "3"? Just asking because ordinarily deprecated vs. terminally deprecated is very specific to the manner in which a program element is deprecated and I assume you don't want this event grabbing the general name for a very specific event setting.
