An element management system in which: a list of fully-qualified versions of network elements is maintained, and the interface to each network element is managed in accordance with the highest fully-qualified version which is no later than the network element's actual version date, EVEN IF there is also a fully-qualified later version. By specifying a "managed level" which is fully qualified and is guaranteed not to be later than the actual revision of the network element, the possibility of hidden incompatibility is reduced. (Network elements are expected to be backwards compatible, but the addition of features may introduce some hidden forward incompatibility.).
