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.
