Types. 

Industrial
Residential
Commercial
Education
Hospital
Station
Civic/government

And a corresponding generic building. 

You can have a landuse=retail to define a mall's area, and a few 
building=retail for the buildings on imagery. Or map the endless myriad of 
building types on top (mall anchor, shed, parking garage, etc). 

But there should be an appropriate landuse to sit under every single building. 
- becaise most "locations" are larger than their building - and denoting the 
full extent of the location is often WAY more important than the actual 
building. Airports, malls, military bases, shopping centres, car dealerships, 
gated communities, and many other locations are usually a lot bigger than their 
buildings. Most locations built for cars are twice the size of the building! 
And stand-alone buildings are pointless until they are grouped by the sets that 
have been put into (a school, a city hall, a shopping centre, an apartment 
complex, a steel parts manufacturing plant) - so a landuse should exist for 
each class of landuse. 

Conveying the actual size of any location with landuse means when you zoom out 
far enough and the (unimportant) building disappear, you can still see the 
general layout of the city. 

Why do we only bother to do that with some landuses and not others?
