To get it perfectly right every string should have a base URI property.
String literals get the base URI of the script element they are in. But
then you would have to do this for every string generating item in the
browser. F.e. the base URI of a string from input.value should probably
be the base URI of the input element.
In any case I don't think it is correct to choose between windows, you
should choose between base URIs of script elements.
