I've been doing this for a while for some buildings.
tiles at home will render building=* as a building so I tend to add this to
anything I want on the map. It would be good to get this added to mapnik
as well. Using the * is nice because we don't have to define every
building type up front, and it's sensible to render most building
outlines in the same way.
