title: Zend validators and error messages: addValidator and addErrorMessage
body: <p>If I have a form element that has multiple validators attached to it (3 in this example), how would I use <code>addErrorMessage</code> to create custom error messages when each unique validator fails. Is there a way to add a custom message for each validator?</p>
  
  <pre><code>$element = new Zend_Form_Element_Text()...
  $element-&gt;....
          -&gt;addValidator(...)
          -&gt;addValidator(...)
          -&gt;addValidator(...)
          -&gt;addErrorMessage()
  </code></pre>
