In the last section, we had an example showing a "date of birth element":
<div class="element">
<?php echo $form->dateOfBirth->renderLabel() ?>
<?php echo $this->formText('dateOfBirth[day]', '', array(
'size' => 2, 'maxlength' => 2)) ?>
/
<?php echo $this->formText('dateOfBirth[month]', '', array(
'size' => 2, 'maxlength' => 2)) ?>
/
<?php echo $this->formText('dateOfBirth[year]', '', array(
'size' => 4, 'maxlength' => 4)) ?>
</div>
How might you represent this element as a Zend_Form_Element?
How might you write a decorator to render it?
