Greetings!
The first condition of the global validation rule for 6.7, overlap
declaration, provides:
> /t1/ is not a subtype of /t2/ (or vice versa), and
Err, but isn't the "overlap" of a supertype/subtype relationship between
two topics different from say the overlap of a topic being of type
father and also of type employee?
That is to say that shouldn't I be able to distinguish between saying
that t2 may be a subtype of t1 versus t2 may overlap with t1?
As I read the declaration and global validation rule, those two cases
are being treated as the same?
Yes?
That seems deeply problematic to me.
Hope everyone is looking forward to a great weekend!
Patrick
