 From that, I would read that location is something that doesn't move,  
e.g. a town - an identifiable geographic place. An object/person has a  
property called position that identifies its current location.

So, anything that can move has a position, and everything that can't  
move (and this may include buildings, monuments etc) has a location. A  
position of course, can be mapped to a location (e.g. to calculate  
nearby locations).
