Is this missing, say, between two calc()s, or not?

I see three points why we should just say "yes, as usual"/"as usual" and
link to css3-values for some of the "Animatable:"/"Computed Value:" lines.

1. The "Animatable:" lines are long and redundant (even worse if calcs()
are added in).

2. This would prevent us from casually changing the lines to have
different semantics. As I pointed out before, for 'background-image',
CSS 2.1 uses

  # Computed Value: absolute URI or none

but CSS3 B&G uses

  # Computed Value: as specified, but with URIs made absolute

. These are semantically different in an environment where not every
URIs can be made absolute (i.e. invalid URIs).

3. "Computed value: absolute length" doesn't seem to cover the calc()s.
