4.8 Port Group Types
The PortGroupType class is a concrete subclass of the Classifier class as illustrated in Figure 24. A PortGroupType class has an extends reference association and an inverseOf reference association to objects of the same class.  Similar to a component type, it contains a features subclause that is represented by the PortGroupFeatures class.  The PortGroupFeatures class has containment associations to the DataPort, EventPort, EventDataPort, and PortGroup classes.  The specific class name is reflected in the association label resulting in its use as XML element tag.
