body: <p>Which advantages have definition list (<code>&lt;dd&gt;&lt;dt&gt;</code> etc..) and when we should use it?
  (Example: use in Zend_Form, but i dont understand why)</p>
  
  <p>Does exist other better options?</p>
  
  <p>(I beginner, but its look to me that is xml use inside html.
  If I right XML not wide used recently because yaml, file.ini, json each of them in their field more efficient in parsing then xml format.)</p>
  
  <p>Thanks</p>
