Hi John,

Thanks, this is a great starter (and crystal clear) example!

* Your 'locn:representativePoint' predicate would be the equivalent of 
the 'ex:aCentroid' of Frans?
* I'm not sure I understand the difference between your proposed 
'locn:extent' predicate and the existing 'locn:geometry' predicate, 
except the later is loosely defined. Is the same thing?
* What about the MBR? Is just another 'extent' (polygon) or should it 
have a specific type because we want to say something about it?
