return<EOL>
Tests if this user can alter agent/agency 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
        lookup operations to unauthorized users.

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