The wood is part of the university, but it should be rendered as if  
it were a hole in the university, right? I think this situation would  
best be described by a relation that states that some area lies  
within some other area (just use type=is_in?), which would be treated  
like a multipolygon relation by the renderers. Is there a more  
obvious way that I'm missing, obsessed with multipolygons as I am?
