 * A generalization is a taxonomic relationship between a more general classifier and a more specific classifier. Each instance of the specific classifier is also an indirect instance of the general classifier. Thus, the specific classifier inherits the features of the more general classifier.
 * A generalization relates a specific classifier to a more general classifier, and is owned by the specific classifier.
