     *
     * Form elements that have been declared "required" and not set will prevent the form from being
     * submitted. Additionally, each element class may provide its own "renderValidationJS" method
     * that is supposed to return custom validation code for the element.
     *
     * The element validation code can assume that the JS "myform" variable points to the form, and must
     * execute <i>return false</i> if validation fails.
     *
     * A basic element validation method may contain something like this:
     * <code>
     * function renderValidationJS() {
     *            $name = $this->getName();
     *            return "if (myform.{$name}.value != 'valid') { " .
     *              "myform.{$name}.focus(); window.alert( '$name is invalid' ); return false;" .
     *              " }";
     * }
     * </code>
     *
     * @param boolean $withtags Include the < javascript > tags in the returned string
     *
     * @return string
     */
