--------------------------------------------------------------

[~mandy_chessell] I am looking at Locations and notice the nestedLocations. It seems that
we should have this is a containment relationship. I suspect with physical locations - this
could be composition, with a single parent location. I suspect in other cases Aggregation
might be more flexible. 

At the moment I am thinking we should at least use aggregation and many to many. I am thinking
we should special case physical location and have a composition hierarchy (though disputed
territories might not fit here) - I could see this as being more intuitive than a many to
many aggregation? 

On 0030. I think OperatingPlaform should have a supertype. Do we count this as infrastructure
or have it as a Referenceable? 
Also I wonder around HostOperatingPlaform relationship, could we have an aggregation relationship
with the platform aggregating hosts?
