 * 1) If the "Supercategory" parameter is supplied, but Category:Supercategory by nationality  does not exist, then  Category:Supercategory  will be used instead)
 * 2) When the "Supercategory" parameter is not supplied, the template tests for the existence of Category:Profession by nationality  . If that does not exist, then  Category:Profession  will be used instead)
