public abstract class Feature<T extends M3Node>
extends M3Node<T>
implements NamespacedEntity, IKeyed<T>

A Feature represents a characteristic or some form of data associated with a particular concept.

For example, an Invoice can have an associated date, a number, a connection with a customer, and it can contain InvoiceLines. All of this information is represented by features.
