I don't think that captures all possible formatting because CSS in
particular has interesting effects when combined with other styles. What I
meant is that we can't test every combination of all CSS properties & HTML
elements (i.e. enumerating every possible DOM with every possible
combinations of CSS properties applied every possible way on each DOM)
simply because there are infinitely many of them. Although I'd guess that
some of them are reputations so we might be able to find a finite subset
that suffice the purpose. anyhow, I agree that testing every CSS property
and every HTML element will be a good idea.  That'll at least give us a
starting point.
