 * - creation context support. The constructor accepts the parent container
 *   instance, which is then used when creating instances.
 * - plugin validation. Implementations may define the `$instanceOf` property
 *   to indicate what class types constitute valid plugins, omitting the
 *   requirement to define the `validate()` method.
 *
 * The implementation extends `ServiceManager`, thus providing the same set
 * of capabilities as found in that implementation.
