The :not() pseudo-class described in the CSS3 selectors CR [1] doesn't
allow this, since the argument to the pseudo-class is permitted to be
only a simple selector.  The CSS3 selectors draft uses the CSS3
definition of simple selector [2], not the CSS2 definition [3].  Had the
CSS2 definition been maintained this would be less confusing (although
there would have to be a new term to describe the thing that is allowed
as the argument to the :not() pseudo-class).
