Zend will ship its elements with tags of dd dt
But if you want to get only the element with out decorator being around it.
you can do:
$this->addElement('text', 'you_element', array( .... 'decorators' => array('viewHelper'), .... ));
But if you want to display errors along with the HTML format,
add errors in the decorators array
This should give you only the element that you can implement your own decorator around it
