That's good to know. It gives us confidence that the proposed change
will bring the specification into line with implementations (and
common sense, since I believe the implementations are doing what is
most intuitive in this case).

I think the keyTimes issue is a bug (and that Cameron's test is
correct) since I believe SMIL does say that keyTimes apply to
to-animation as well[1] but I'm not fussed whether the proposed
keyTimes wording ends up in the spec or not.

Thanks again Alex,
