Hans,

excuse my top-posting.

I was really interested in this thread. But Dutch isn’t something in
between English and German (two languages I used to know).

My apologies for the comment, if the message was intended as private.

I’m eager to learn XML in ConTeXt, since the possibilities are less than
with standard (or the other) ConTeXt.
