order for the SRM to enforce it. Currently, enforcement of space usage autho-
rization is not uniformly supported by SRMs either. Adding such capabilities
requires keeping track of usage by each user or group of users and providing
a reporting mechanism to VOs. Security mechanisms have to be in place as
well, in order to verify that a request is vetted by the VO.
