Some more words on this subject. Regarding attribute selectors, some people can
claim: "Wait a second, "[class="test"]" is really simple selector and notation
:not([class="test"] works as expected in Firefox and Opera and of cause in
Webkit"? 

So is a [class="test"] really simple selector? No! Take a look on this fragment
in specification:

"The universal selector, written "asterisk" (*), represents the qualified name
of any element type.[...]

If the universal selector is not the only component of a sequence of simple
selectors, the * may be omitted.

Examples:

*[hreflang|=en] and [hreflang|=en] are equivalent"

[http://www.w3.org/TR/css3-selectors/#universal-selector]

So this case "[class="test"]" is a simplified version of "*[class="test"]" and
it is a sequence of simple selectors. Both cases a logically equal. So in my
opinion, it's absolutely incorrect that this case  :not(*[class="test"]) -
which is logically equivalent to :not([class="test"]) - does not work in
Firefox and Opera, .

Take a look at an attached test case.

Ian, you are an editor of CSS3 Selectors specification. what you think about
this issue?
