For this to work, IMHO there must be some notion of "structural equiv= alence" of the shadow root with respect to the original root. In the exampl= e, apparently the declaration "subtype T is Foo.T;" in the Shadow package s= pec creates the structural equivalence. Meanwhile, I've been able to successfully build the example using an old Ap= ex-3.2.0b. I'm still not sure of chapter and verse in the RM that defines this. -- Oliver
