OCL constraints should be able to specify these restrictions, and
Papyrus Luna evaluates such constraints in validation of models that
have the profile applied.

Let's call the class stereotype "Client". Then an OCL constraint like
this (totally untried and untested) on the dependency stereotype might
do what you want:
I'm assuming the cast as Class will be needed to resolve the Client
stereotype's metaclass extension end.
> Another issue is the stereotype properties. How are they modeled?
I don't understand the question. They are modeled like any other
properties of a class in a Papyrus UML model, or do you have a more
specific concern about how they work at run-time?

The new OCL 2.4 selector "->selectByKind(uml::Class)" might simplify the definition of the constraint (You don't need to cast anymore, since it's a mix between select() and oclAsType()).
To display the stereotype properties in the diagram, you need to select a stereotyped element in the diagram, then go to the Properties view, Appearance tab, select the stereotype property and click the "display" button. Then, you can choose to display it in a Compartment (default) or as a Comment ("Display place", in the same tab of the properties view)

Thank you Klaas for answering..
I know that Luna is better, but it doesn't take account about the shape format of a stereotype, that's why I prefer Kepler...
Doesn't matter, I work on Luna at the same time..
About the second tip, do you mean by OCL Syntax completion, the OCL Xtext assistant (ctrl+ space)? and what is UML spec? sorry, i want to understand this vocabulary.
Yes I mean the OCL syntax completion. UML spec = UML specification.
But looking at your profile, it looks like you've understood this pretty well
I uploaded the profile and a model to test the constraint.
Thank you again..
The profile is quite big (which makes it harder to debug/understand).
My first problem with the profile: why do you extend the meta-class Extension to create a ViewExtension stereotype (instead of extending an association)? Are you aware that Extension is a special meta-class, not to be used in a standard model? Or do I miss something in your profile?
