My bad. I often run stylesheets against themselves for the sake of
convenience when I don't require an input document. I should've
mentioned that in my first post and obviously, it won't work the minute
I change this practice.

I wasn't aware of the existence of that function (odd, considering we
implemented and tested it). But this looks like exactly what I needed.

A lot of buts, but a workaround that could work in trivial
circumstances, thanks.
