I just stumbled accross the English(Ferdinand Zvonimir von Habsburg) and German(Ferdinand Zvonimir Habsburg-Lothringen) version of a descendant of the Austrian Nobility. In the English version the name of the person includes a von (engl. of). But I thought the Adelsaufhebungsgesetz made it illegal for him and his family to have the von in his name.
So my question: Is this ban only valid in Austria or should it be changed on wikipedia?
