I believe that this is not a viable solution.

For example, under this scheme

	Class(Person partial)
	Individual(john annotation(ex a) type(Person))
	Individual(jack type(Person))

	Class(Person partial)
	Individual(john type(Person))
	Individual(jack annotation(ex a) type(Person))
	SameIndividual(john jack)
