IMHO they are both, properties of other features but can be features on their own. Every address should exist just once, similar to how every route should exist only once (e.g. motorway 1), but it doesn't mean there will be only one object in osm with ref=M1 (e.g. if you add the ref to the ways which are part of M1 rather than to a relation for both directions). If something only exists once in the world does not mean we can't have several objects pointing to it.
