I never found a way of fixing that without totally screwing up the
layering of the parser, which assembles entities at level where there is
no knowledge of the syntactic context. I've never understood why XML
mixes up its layers so badly.

If I had more hours in the day, I would be happy to spend them on
bringing it up to scratch. Sadly, I haven't!
