I know that. But special parsing rules, just as new CSS properties,  
need changes to happen in the browser. If someone is going to improve  
the browser, it'd be much better to improve the presentational layer  
with a few reusable CSS rules than to add a collection of specific- 
case parser rules changing the DOM for presentational reasons.

And that's why I was asking for better support, not design, in the  
sentence above. I mentioned they were meant to stack in case someone  
missed that from one of the previous 195 messages of that very long  
thread, but I admit it could have been formulated better.
