This makes :not() much clearer, but as David pointed out in
there is still a bug in both css 2.1 and css3-selectors, since
the grammar does not allow a pseudo-element by itself as a valid
selector, conflicting with implementations and possibly css1
(I don't see a concrete statement either way in
but am happy to go with David's assessment).
