We've already accepted that order will matter for cases like

   interface A {
     void f(B x);
     void f(C x);

for when an object might implement both B and C (at least in theory).

I agree that with "Node or DOMString" you're much more likely to get a 
useful result from converting the JS value to a string rather than a 
Node.  Is that going to be the common case to warrant choosing DOMString 
over the Node?  What about other types like "Node or float" or "Node or 
DOMString or float"?

Or should we make order within the union type matter here too?
