Well, as I tried to make clear in my examples, it affects both
because it alters the base URI of the document *prior* to any
further resolution. I was only trying to clarify that we weren't
talking about IDs (which I thought was a resolved issue, but was
apparently not), but about references to IDs. You're correct
though -- the base URI of the document affects both, and xml:base
alters it for both.
