  * Provides methods for an entity to support revisions.
+ *
+ * Classes implementing this interface do not necessarily support revisions.
+ *
+ * To detect whether an entity type supports revisions, call
+ * EntityTypeInterface::isRevisionable().
+ *
+ * Many entity interfaces are composed of numerous other interfaces such as this
+ * one, which allow implementations to pick and choose which features to.
+ * support through stub implementations of various interface methods. This means
+ * that even if an entity class implements RevisionableInterface, it might only
+ * have a stub implementation and not a functional one.
