Or man_made=canopy? http://en.wikipedia.org/wiki/Canopy_(building) I
think I'm going with man_made=canopy.
But that doesn't work for "a building with a contiguous floor over a
parking area", unless you "split the building", in order to use
multiple layer tags. The building exists at both layer=0 and layer=1.
Honestly, I don't like covered=yes here. It's a hack, but unless and
until there is support for true three dimensional mapping, any
solution is going to be a hack.
Splitting the building into two parts, one at layer=0, touching the
parking area, and one at layer=1, encompassing both the area next to
and under the parking area, is another solution. It's similar to what
we'd do with a highway when we want it to exist at multiple layers.
But it's probably unprecedented for buildings.
