It's not immediately clear to me what's happening here, but I suspect that
the problem might not be with the URI passed to unparsed-text(), but rather
with the base URI of the stylesheet. Although in principle when you supply
an absolute URI to unparsed-text() it shouldn't matter what the base URI is,
in practice it might well be that problems with the base URI get reported on
this path.

The most likely reason for a problem with the base URI is that you didn't
call setSystemId() on the Source object defining the stylesheet.
