Hey,
I am stuck with the namespace mechanism. Reading the specs over and over
again, many things remain unclear to me, e.g.:
Suppose the class AClass is owned by a package A. Now AClass want's to
have a property of type BClass, which is owed by a package B.
Intuitively, this is only possible if the visibility of BClass is
public. I'd really rely on the specification to confirm this, but
reading it is a nightmare. I therefore experiment with the API and
created an example model that reflects the above structures. Contrary to
the intuition, even if I make BClass private, I can assign BClass as the
type of a property in AClass, and validation completes successfully!?
The model is attached. So there's two possibilities:
a. My intuition is wrong
b. The validation check is wrong / incomplete
Thanks for your comments.
Felix
