Getting PassiveTeX to work with DocBook

[Justus Piater <Justus.Piater@ULg.ac.be>]

Due to recurring requests, here's how I get PassiveTeX to work with
recent DocBook XSL-FO style sheets. Note that this is not a general
solution; I took some radical measures that work for me but may be too
restrictive for other users; you may have to tweak some of my
hard-wired parameters or generalize some templates. It may also be
incomplete in that constructs that I have not yet used cause
PassiveTeX problems unknown to me.  But it's a starting point that
should get most real-world DocBook files to convert to PDF.
