Thanks for your in-depth explanation, Ulrike, but I'm afraid I don't 
understand a word (sorry, but it is too complicated for me).

My LuaTeX version is beta-0.60.2-2010071217 (TeX Live 2010) (rev 3736).

BTW, is the sample document above supposed to work. (I'm afraid it doesn't.)

Thanks for your help,


Pablo
