I suppose the FAA way of saying it suffices for the rest of the world i.e.: "Turn left heading 270, maintain 2000' til established, cleared ILS 24".
WRT the suggestion made in the first post, about stating "cleared localiser", i would interpret that as an approach clearence, for flying a localiser only approach. I would expect to hear "join the localiser, maintain xxxx feet" or something similar to join the localiser without descending.
