title: Customizing the Rendering of a Zend_Form_Element_Radio
body: <p>I have an object that's an instance of a Zend_Form_Element_Radio.  I'd like to customize how these radio buttons are displayed.  The <a href="http://framework.zend.com/manual/en/zend.form.standardElements.html" rel="nofollow noreferrer">manual</a> remarks</p>
  
  <blockquote>
    <p>Radio elements allow you to specify several options, of which you need a single value returned. Zend_Form_Element_Radio extends the base Zend_Form_Element_Multi class, allowing you to specify a number of options, and then uses the formRadio view helper to display these.</p>
  </blockquote>
  
  <p>However, I'm not picking on the context of a HOW the formRadio helper should be used, and how that would allow me to customize the display.  </p>
  
  <p>Before I dig too deeply into the Zend source, is there something obvious I'm missing, and/or a straight forward explanation of the intended use?</p>
