It's always been the case that SVG extends the set of events that
can be used within the event-value syntax. I'm not sure why (or if)
this upsets you, since I expect it to be common that a host language
has a different set of supported events than SMIL.

What do you mean by plain?

That's right, there is no requirement.

Yes. This is because the feature is already supported via DOM, which
isn't the case with SMIL. It was never a requirement for the
feature set of SMIL animation to match the feature set of scripting.

Could you suggest a solution?
