@abc.abstractmethod<EOL><INDENT>def can_assign_relationships_to_family(self, family_id):<DEDENT>
return<EOL>
Tests if this user can alter relationship/family mappings.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known mapping methods in
        this session will result in a ``PermissionDenied``. This is
        intended as a hint to an application that may opt not to offer
        assignment operations to unauthorized users.

        :param family_id: the ``Id`` of the ``Family``
        :type family_id: ``osid.id.Id``
        :return: ``false`` if mapping is not authorized, ``true`` otherwise
        :rtype: ``boolean``
        :raise: ``NullArgument`` -- ``family_id`` is ``null``
