Thank you, it seems to work much better !There is still the problem that "node.has_attribute" does not return "nil" when I expect it should, but that is luatex problem (a check that a parameter is really an integer should be performed before calling lua_tointeger), so I will change mailing-list in order to report it.
Faithfully yours, Stéphane Goujet.
