You only need to worry about this for fuzzy locations. The coordinate 
policy in effect essentially determines what you consider as the start 
coordinate for a location like <1..10 and similarly for the end 
coordinate. At the time consensus could not be reached and so we 
designed this API that lets you have your way if you can implement it 
as a policy object. There's some default ones two for the most common 
cases (use max, use min, etc).
