**A bit more XML than CSS**

OK, I would just like to clarify this point, so I'm clear what the  
situation is.

I'm not too hot on my XML, but after having done some research on how  
ATTLIST declarations are able to map name-value pairs with elements,  
and xml:id, it appears that only one token is allowed for type ID. Are  
you saying that DOM3 (I presume you mean this feature? (http://www.w3.org/TR/DOM-Level-3-Core/core.html#Attr-isId) 
), extends this so we're able to match a subset of ID tokens, like we  
can currently with the class attribute in HTML? If this is the case,  
then #valid#selector would presumably correctly match the space- 
separated type ID values, 'valid' and 'selector'.
