 * <!-- begin-model-doc -->
 * A classifier is a namespace whose members can include features. Classifier is an abstract metaclass. A classifier is a type and can own generalizations, thereby making it possible to define generalization relationships to other classifiers. A classifier can specify a generalization hierarchy by referencing its general classifiers. A classifier is a redefinable element, meaning that it is possible to redefine nested classifiers.
