Hi James, Assuming we have a "top level" bundle (I am not sure what it would be exactly), I don't think that the two expressions you are suggesting are equivalent. specializationOf(e1,e2,toplevelBundle) indicates that e1 shares all aspects of e2 and presents a further aspect: the bundle toplevelBundle. specializationOf(e1,e2) indicates that e1 shares all aspects of e2 and presents and further specific aspects (but without indicating which ones): a bundle MAY or MAY NOT have been fixed.
