title: jQuery Validate plugin: input vs. textarea
body: <p>I'm wondering why there is a difference in jQuery Validate plugin's default handling of <code>&lt;input&gt;</code> vs. <code>&lt;textarea&gt;</code>. In the demo below, notice that the <code>required</code> class makes the <code>&lt;input&gt;</code> required but not the <code>&lt;textarea&gt;</code>.</p>
  
  <pre><code>&lt;form&gt;
      &lt;input class='required' /&gt; 
      &lt;textarea class='required' &gt;&lt;/textarea&gt;
      &lt;button value='submit'&gt;submit&lt;/button&gt;
  &lt;/form&gt;
  
  $('form').validate();
  </code></pre>
