This was discussed in details several times in the past. The reason is this: - FAMIXClass is only one of the subclasses of FAMIXType. - When working with systems like Java, you get in your model many types that are not FAMIXClass (e.g., FAMIXParameterizedType which models a specific generic type) - When atClassScope was first created, #methods and #attributes were defined in FAMIXClass. In the meantime, we generalized the model, and we now have FAMIXType defining #methods and #attributes. The subtypes of FAMIXType are now responsible for handling only extra semantics. So essentially, the old atClassScope does correspond now with atTypeScope.
