023 * Base implementation of {@link ComponentDefinition} that provides a basic implementation of
024 * {@link #getDescription} which delegates to {@link #getName}. Also provides a base implementation
025 * of {@link #toString} which delegates to {@link #getDescription} in keeping with the recommended
026 * implementation strategy. Also provides default implementations of {@link #getInnerBeanDefinitions}
027 * and {@link #getBeanReferences} that return an empty array.
