   * form is located in the parent form, #parents and #array_parents must be
   * known, but these are not available during the initial build phase. In order
   * to have these properties available when building the plugin form's
   * elements, let this method return a form element that has a #process
   * callback and build the rest of the form in the callback. By the time the
   * callback is executed, the element's #parents and #array_parents properties
   * will have been set by the form API. For more documentation on #parents and
   * #array_parents, see \Drupal\Core\Render\Element\FormElement.

   * @param array $form
   *   An associative array containing the initial structure of the plugin form.

   *   state created through
   *   \Drupal\Core\Form\SubformState::createForSubform().
   *
   * @return array
   *   The form structure.
