 * @class Ext.form.HtmlEditor

 * <li><b><code>success</code></b> property : Boolean
 * <div class="sub-desc">The <code>success</code> property is required.</div></li>
 * <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>

 * {@link Ext.form.Action#result result} property.</p>

 * @class Ext.form.VTypes
 * <p>This is a singleton object which contains a set of commonly used field validation functions.
 * The validations provided are basic and intended to be easily customizable and extended.</p>
 * <p>To add custom VTypes specify the <code>{@link Ext.form.TextField#vtype vtype}</code> validation
 * test function, and optionally specify any corresponding error text to display and any keystroke
 * filtering mask to apply. For example:</p>
 * <pre><code>
// custom Vtype for vtype:'time'
var timeTest = /^([1-9]|1[0-9]):([0-5][0-9])(\s[a|p]m)$/i;
Ext.apply(Ext.form.VTypes, {
    //  vtype validation function
    time: function(val, field) {
        return timeTest.test(val);
    },
    // vtype Text property: The error text to display when the validation function returns false
    timeText: 'Not a valid time.  Must be in the format "12:34 PM".',
    // vtype Mask property: The keystroke filter mask
    timeMask: /[\d\s:amp]/i
});
 * </code></pre>
 * Another example: 
 * <pre><code>
// custom Vtype for vtype:'IPAddress'
Ext.apply(Ext.form.VTypes, {
