Thank you for that quick help. But sorry, I didn't figure out what it 
does, anyhow your testfile doesn't work yet ( mean it prints still 
normal old style numbers and no superscript numbers), and when writing a 
footnote (which triggers the supersript) I get following message:

! Font \zf at basefont="" not loadable: installed font not found.
<to be read again>
                   \zf at family@fontdef LinuxLibertineO(0)

Obviously it is looking for a new font definition (0?)?

Hm, I seem to have had an old version of xltxtra, this option doesn't 
exist yet. I just updated and this works fine, since it is only for 
those numbers I can live with it for the moment.

Thank you for that solution!
