           Summary: More clarification for argument in :not() and
           Product: CSS
           Version: unspecified

Hello, in new module Selectors Level 4 we can use a selector list as an
argument in :not() and :matches() pseudo-classes. But it will be nice (better)
if one example will explain this case:

div:not(.heavy, #box) {color: red}

What exactly does it mean:

div:not(.heavy):not(#box) {color: red}


div:not(.heavy), div:not(#box) {color: red}


div:not(.heavy) {color: red}
div:not(#box) {color: red}

Case1 and Case2 is not the same. Case2 will style <p class="heavy"> (second
rule) and <p id="box"> (first rule), but Case1 no.

Maybe term's selector list in some way shown it, but one simple example can
replace many long descriptions and uncertainties.

The same situation is for :matches(). I check it for :-moz-any() pseudo and it
works like Case2. But dont know if :-moz-any() is or will be equivalent for
:matches(). At this moment there is no browser with implements the new module,
so we can't test anything.

On the other site, if not() and :matches() represent Case2, maybe consider
adding next selector which represents Case1, like notAll(), matchesAll(),
additional modyficator/identificator or sometching else. It can be short
version for unnecessary repeat :not(), like:



Last thing is unnecessary, I see in new level 4 we can sth like this:


and you considering multiple-value matching:

:not([arg=val1,val2,val3,val4,val5,val6]) << but again I wander what comma will
means, conjunction or alternative.
