The spec is quite incomplete without the "TODO" describing which properties
are animatable and how they animate. For example, some <number> values are
required to be integers, so I'm not sure how you animate 'column-count' for
example; maybe some <number> properties should not be animatable.

The spec need to define how colors interpolate.

It seems to me that supporting step functions as transition functions might
be very useful.

The issue at the end of section 2.5 is important. A useful experiment for
evaluating animation proposals is to try to implement the OS X dock's
behaviours, and that issue comes up immediately --- I gave up on SMIL when I
couldn't figure out how to handle that :-).

"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
