I think of it more like that null is the actual namespace URI value, and

something the method should handle, rather than something the bindings
worry about.
But the method signature in IDL is DOMString. So by the time it sees the
argument, it will be a DOMString. The only question is which DOMString.
In Gecko, if you pass in "" it will see the string "".
If you pass in null, it will see a string that is equal to "" but has a "this is
a null string" bit set.
Conceptually, the latter is more like a |char * str = NULL| and the former is
more like a |char * str = "";| but both represented by a String object of some sort.
It might make sense to declare this the default conversion of null to DOMString
and then have NoNull mean that the Object.prototype.toString conversion should
be used instead.
