I don't really see how it could be simple, since you need a hierarchy of 
controls, and an AnewtForm is flat. Sure you could flatten it, and 
during processing blow it up again, but that's what I meant with 
'cumbersome'.

Ideally what I would want is this:

class TextForm extends AnewtForm {
  function __construct($text) {
    // add controls for title, introduction, text
  }
  function handle_valid() {
    save_something($this->get_control_values());
  }
}

class ProductForm extends AnewtForm {
  function __construct($product) {
    // some basic controls
    foreach ($product->get_texts() as $text) {
      $c = new AnewtFormControlSubForm(new TextForm($text));
      $this->add_control($c);
    }
  }

  function is_valid() {
    return parent::is_valid() && $this->subforms_valid()
  }

  function handle_valid() {
    $this->process_subforms();
  }
}

Possibly those is_valid() and handle_valid() definitions automated.
