[whatwg] Unifying DOMTokenList with DOM 3 Core's DOMStringList?

[Adam Roben]

DOM 3 Core defines the DOMStringList interface [1], which has some  
similarities to HTML 5's DOMTokenList interface. In fact,  
DOMStringList basically provides a subset of DOMTokenList's  
functionality. But there is a mismatch in the names of the  
DOMTokenList.has and DOMTokenList.contains methods (which seem to have  
the same purpose).

I think DOMTokenList.has should be renamed to DOMTokenList.contains,  
to match DOMStringList.

Perhaps some relationship between these two interfaces should be  
defined as well (though that would obviously introduce a dependency on  
DOM 3 Core).
