Hi!
Just wondering - is there a reason why there is an anonymous
UML-specific subclass of Diagnostician hidden inside the
UMLActionBarContributor? Wouldn't it be reasonable to provide a public
UMLDiagnostician so that others can use it, too?

Hi Ed,
I agree that the Diagnostician might not be the most flexible validation
technology because it only validates predefined static model
constraints, but it is a very simple way for validating syntactical
correctness. The anonymous subclass for UML mentioned before only adds
validation of stereotype applications and reports them at the
stereotyped elements because the stereotype application are located
elsewhere in the resource. As I see it, this is an essential part for
syntactical model validation.
The anonymous validator does not add anything else, and we do not want
add anything else either here (we have a separate additional
domain-specific validator). We don't use OCL or Papyrus.
So I'm asking again, what about providing a UMLDiagnostician that
extends the EMF Diagnostician with the aforementioned validation of
stereotype applications?
At the moment, we duplicated that particular code in our project...
Cheers
Patrick
