I did something like this recently by creating a custom decorator that
created the small bit of markup I needed and attaching it to the form:

    My_Form_Decorator_RequiredNotice extends Zend_Form_Decorator_Abstract
    {
        public function render($content)
        {
            return $content
                 . '<span>* Required</span>';
        }
    }

    $form->addPrefixPath('My_Form_Decorator', 'My/Form/Decorator/', 
'decorator');
    $form->setDecorators(array(
        'FormElements',
        array('HtmlTag', array('tag' => 'dl')),
        'RequiredNotice',
        'Fieldset',
        'Form',
    ));

For this, I'd take the example above, but allow optionally specifying a
"content" option to the decorator:

        public function render($content)
        {
            if (null === ($markup = $this->getOption('content'))) {
                $markup = '* Required';
            }
            return $content . '<span>' . $markup . '</span>';
        }

Then, when instantiating, you'd do this:'

    $form->setDecorators(array(
        'FormElements',
        array('HtmlTag', array('tag' => 'dl')),
        array('RequiredNotice', array('content' => 'My custom notice!')),
        'Fieldset',
        'Form',
    ));

Hopefully the above will help.
