It needs to for many standard DOM methods. Most core DOM methods that  
take namespaces treat a null namespaceURI or prefix parameter the same  
as the empty string, not the same as the string "null". As mentioned,  
I advise looking at WebKit's IDL files since we have represented most  
of the weird cases there. I think the empty string conversion may  
actually be somewhat more common in DOM APIs, although it is not the  
native ECMAScript string conversion behavior.
