Thank you, Siarhei, for the explanation of the interrelationship between JEuclid and FOP. In fact that was roughly what I mean by "image". As I explained, I am not in the details.
The words by Jeremias, that you can not place all element properly, might be the point that sounds the most important to me. Does anybody know if there is an approach like that one Vincent wanted to try, but has not find the time for? You are most likely right, Jeremias, but ... I think the way to convert MathML to XSL:FO is more natural. Maybe here are some people who give this a try. If so, please contact me via private email. Regards, Norman Markgraf
