If the goal is just to implement someone else's standard then we can't use the wisdom of the community here to improve the tag, therefore I'm not too fussed about making this match what another project is using, instead we should aim to have the best tags and documentation as the outcome of this proposal process. Then if that's different, other projects closely tied to OSM can migrate to the OSM community accepted schema.
