A note: the Philippines is actually a one-based system (first floor =
ground floor) because our economy follows the U.S. as a result of being a
territory of the U.S. before and during WWII. The fact that you get more
zero-based level=* tagging in OSM for the Philippines is because of mappers
like me who actually do read the wiki and inform other new mappers of OSM's
system.
