You can't.

You can't do it for fields, but you can do it for the form if at least submit button is forms-generated.

$form = new Form();
$form->addSubmit('submit');
$form->onSuccess[] = function () {
	$data = $form->getHttpData($form::DataText, 'sel[]');
	if (...) { // validation
		$form->addError('...');
		return;
	}

	// handle if ok
};
