Per spec, but do you know if the only reason that these are nullable on event
interface and dict is so that scripts don't have to provide a value? If the UA
itself can never fire events where either of these are null, I'd suggest
changing the spec to make the dict and its members required and everything
non-nullable. This file would shrink a bit.
