‘Module – ModuleClass’ relationship
Misleading description in current SDT3.0: “The relationship between a ModuleClass and a Module is very similar to the specification of a class and an instantiated object in an object oriented programming language.”
Actually it’s clearly defined as ‘subclassing’ according to the UML diagram (but it’s not explicitly reflected in the xsd either)
Suggestion: to revise the text to “… a superclass and a subclass …”
