Random thoughts:

Does this really buy anything compared to overlapping polygons (except, 
obviously, where the polygons are coincident, in which case it saves a 

I’m a bit nervous that primary/secodary/tertiary is a bit too fuzzy. In 
a city, primary is street level, secondary is above, while in the 
forest, primary is the forest and secondary is what’s on the floor?

With linear objects, such as streets, we gladly chop them into umpteen 
pieces to put the right tags on each piece (this bit is no-parking, this 
stretch is a pedestrian zone, those 50 meters are one-way, all of them 
are named "Main Street"). Do we want to do that for polygons as well 
(extreme case: for every point on the surface of the planet, there is 
exactly one polygon that covers that point and holds *all* the tags that 
apply at that point) or do we want to work with overlapping polygons?
