I'm the one who created the building/building complex property (quite  
awhile ago), and I think that generalizing this to structures is a  
very good idea.

I'm wondering, however, if it might make sense to use "/location/ 
location/containedby", perhaps for both structures and buildings, as  
it's likely that queries for containment might be done in a very  
general way.

We could still have "Building complex" and "Structure complex" as  
types (or even deprecate Building complex) for the "is-a" definition.
