still there are other values like "unknown" and "motor_vehicle" which
seem to make sense to me (I didn't add them myself, as I consider
noexit (no_exit is used just 5 times, so I guess we're talking about
noexit) pointless: that's what a map is for, a router won't need this
tag, and in the end the whole earth is noexit, until we consider
rockets or other spacecraft a possibility)

even housenumbers can be all kind of weird numbers, so limiting the
possibilities doesn't really meet the needs.
