Gets a ``QualifierList`` corresponding to the given qualifier genus ``Type`` which does not include qualifiers of types derived from the specified ``Type``.

        In plenary mode, the returned list contains all known qualifiers
        or an error results. Otherwise, the returned list may contain
        only those qualifiers that are accessible through this session.
        In both cases, the order of the set is not specified.

        :param qualifier_genus_type: a qualifier genus type
        :type qualifier_genus_type: ``osid.type.Type``
        :return: the returned ``Qualifier`` list
        :rtype: ``osid.authorization.QualifierList``
        :raise: ``NullArgument`` -- ``qualifier_genus_type`` is ``null``
        :raise: ``OperationFailed`` -- unable to complete request
