private class ItemLocation from TopLoc

	---Purpose: An ItemLocation is an elementary coordinate system
	--          in a Location.
	--          
	--          The  ItemLocation     contains :
	--          
	--          * The elementary Datum.
	--          
	--          * The exponent of the elementary Datum.
	--          
	--          * The transformation associated to the composition.
	--
