If you really want a default you can do it with 2 levels of generics
and an access-to-subprogram type, as below (not tested). In Ada 2006 I
think you can do without the access type.
generic
type T is private;
package Level_1 is
type Copy_Ptr is access procedure (From : in T; To : out T);
procedure Default_Copy (From : in T; To : out T);
generic
Copy : Copy_Ptr := Default_Copy'Access;
package Level_2 is
...
end;
end;
