I think you'll find most if not all ATC standing agreements are published as 'level notes' in the NATS Standard Route Document, availble on the AIS CD-ROM or via the Eurocontrol AGORA website (you have to register for this). A friend of mine in Brussels says that CFMU are looking are following the UK's lead and publishing all such level info to help ops planners calculate standard fuel-burn profiles, etc..
