That depends on how volatile you think it'll be. If it's reasonably
static then an enumeration would probably be best.

True, but that also means that event recipients have no idea what kind
of values to expect or what they mean.

Ah, I see. That does make it trickier.
I'm not spotting any precedent for doing multiple sub-mappings in an
event. Doing this in positional arguments is simple to parse, but
beside the lack of flexibility mentioned earlier it's pretty hard to
I cringe a bit to suggest it, but maybe a mapping in a mapping?

Positional arguments aren't harder to parse, just harder to read and
more inflexible. I'd be happy to suggest spec alternatives if you
want. Mind if we revise the proposal based on the above first?
