Spidermonkey behaves differently than I state above, for an empty 
XMLList it indeed returns undefined but for the following XMLList it 
returns null while the spec would mandate undefined too:

js> var godList = <><god>Kibo</god><god>Xibo</god></>;
js> print(godList.parent())
null

Rhino returns undefined.
