I should generalize this text a bit, actually: in the first line, "its 
base value" should be replaced with "one of the values that we're 
animating between".

This is because we also need to account for situations where the animation 
attributes |from/by/to/values| have the special "inherit" or "currentColor 
values. (e.g. along with the examples already given, we need to handle 
situations like <animate to="inherit" ...> or <animate from="currentColor" 
...>)
