They aren't relevant for the uniqueness check.  But if the resource contains
validation information of some kind (schema, DTD), the XML processor might use
it for a validity check with respect to that information.

Since I'm advocating it, my first answer would be ``nothing''.  But there's
still design work to be done, and until it's done one can't be absolutely sure
that there isn't a gotcha lurking somewhere.
