    $result->add_error({ name => 'foo' });

This allows you to add custom error messages after the widget has processed the input params.

Accepts 'name', 'type' and 'message' arguments. The 'name' argument is required. The default value for 'type' is 'Custom'. The default value for 'message' is 'Invalid Input'.

An example of use.

    if ( ! $result->has_errors ) {
        my $user = $result->valid('username');
        my $pass = $result->valid('password');

        if ( ! $app->login( $user, $pass ) ) {
            $result->add_error({
                name => 'password',
                message => 'Incorrect Password',
            });
        }
    }

In this example, the $result initially contains no errors. If the login() is unsuccessful though, add_error() is used to add an error to the password Element. If the user is shown the form again using "$result->as_xml", they will be shown an appropriate error message alongside the password field.
