title: placeholder text in zend text element
body: <p>I am working on a Zend form application where my form contains text boxes with watermarks.</p>
  
  <p>we can achieve this in HTML by the following code:</p>
  
  <pre><code>&lt;input type="text" placeholder="Search" name="q" /&gt;
  </code></pre>
