I think it's technically against the rules, but I doubt anyone would care anyway.
What does bother me, is the fact that Rheinlanders don't speak German (except for a few words), so someone who only speaks German and has to resort to a translator to be able to express herself in English is quite a stretch. Except off course if she had been raised in German only, but it would take some quite irresponsible parents to raise someone in a semi-dead language.
