 * <li><b><code>errors</code></b> property : Object
 * <div class="sub-desc"><div class="sub-desc">The <code>errors</code> property,
 * which is optional, contains error messages for invalid fields.</div></li>
 * </ul></div>

 * or event handler methods. The object decoded from this JSON is available in the
 * {@link Ext.form.Action#result result} property.</p>
 * <p>Alternatively, if an {@link #errorReader} is specified as an {@link Ext.data.XmlReader XmlReader}:</p><pre><code>
    errorReader: new Ext.data.XmlReader({

 * <p>then the results may be sent back in XML format:</p><pre><code>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;message success="false"&gt;
&lt;errors&gt;
    &lt;field&gt;
