Почему моя схема JSON неправильно проверяет дочерний объект?

Учитывая приведенные ниже JSON и схему, всеactor.mbox,actor.member[0].objectType иactor.member[0].mboxдолжны дать сбой. Они не. Должно быть что-то не так в моей схеме. Я думаю, что сузил его до чего-то, связанного с определением IdGroup, но не могу найти проблему. Любой гуру схемы json видит что-то явно неправильное?
