Sure, I understand that.  But as Nathan points out, you don't always know
the location of the file you're parsing, especially if you're running in a
web server and the document was uploaded from a web browser or was the body
of an HTTP PUT.  If there's no @base then you just have to pick something
that hopefully makes sense.
