Dear All,

I am a student who is interesting in OCL expression.
I have a question about writing an OCL expression in a
metamodel level.

Assuming that in a metamodel, there is a model element
named "A" which is a mandatory element. 
This element must be constructed as a class in a model

How can we write an OCL expression to restrict this
thing ?

Thank you,
