[Tagging] Car pound, tow pound etc.

[Jean-Marc Liotier]

When the police impounds a wrongly parked vehicle, it takes it to a
managed parking facility where they keep it until the infraction is
resolved. How should we tag that place ?

There are single digit numbers of amenity=pound, amenity=car_pound and
amenity=tow_pound - that seems very little considering the widespread
police practice.

Or should we subtag it as a special sort of amenity=parking,
access=private ? It has also been done that way in quite a few places.
