I wrote that Wiki page and I still think it makes sense. This method
(where there may be additional outers inside inners) also conforms to
the OGC "simple features" geometry rules, i.e. "everybody does it".

Not the browse URL but the "raw XML" URL
(http://api.openstreetmap.org/api/0.6/node/123456) - you can enter that
in JOSM's "open location" dialog (from the File menu). When downloading
ways or relations that way, add /full to the end of the URL.
