   *   - #input: boolean indicating whether or not this element carries a value
   *     (even if it's hidden).
   *   - #process: array of callback functions taking $element, $form_state,
   *     and $complete_form.
   *   - #after_build: array of callables taking $element and $form_state.
   *   - #validate: array of callback functions taking $form and $form_state.
   *   - #element_validate: array of callback functions taking $element and
   *     $form_state.
   *   - #pre_render: array of callables taking $element.
   *   - #post_render: array of callables taking $children and $element.
   *   - #submit: array of callback functions taking $form and $form_state.
   *   - #title_display: optional string indicating if and how #title should be
   *     displayed (see form-element.html.twig).
