That would instantly bring up the need of authors to define alternative
style of rendering in case of a specific @exclude (or any syntax). Even
then, an author will have to do some serious thinking on style
combinations. If I have a red background with a red border and the
@exclude encountered doesn't like the background, maybe my alternative
blue background will work but it will not look good with the red border.
Just an example but you get the point.
Kindest regards,

Subject: Excluding declarations from the cascade

	   Current CSS features allow the user some control over the
	presentation of documents, but it's a rather limited control.
	example some users don't like 'text-decoration: blink' others
	like 'position: fixed', 'background-attachment: fixed', 'cursor:
	crosshair', etc.pp. CSS allows you only to demand a specific
	presentation, you cannot exclude some property/value
combinations. For
	example, to get rid of 'position: fixed' I can only write
	  * { position: static !important }
	but this would override all values for the position property I
_want_ to
	allow, and this would cause problems. Consider
	 * { text-decoration: none !important }
	and the author defines
	 obsololete { text-decoration: line-through }
	the presentation would break. I like to see some feature in CSS
Level 3
	that allows me to exclude distinct values for specific
	instead of overriding them.
	A possible syntax could be a new at-rule, e.g.
	  @exclude {
	    :link, :visited { text-decoration: none                  }
	    *               { position: fixed                        }
	    body            { background-attachment: fixed           }
	    p               { color: silver; background-color: white }
	but maybe others can come up with some better suggestions.
