In the 'Creating custom email notifications' dev. article, the Mailer::register function does not exist in the 5.4.x version, so, when trying to send email, I get a

Call to undefined method XLite\Core\Mailer::register()

error message, so this article doesn't fit in 5.4.x version.

The related code, displayed in the article, concerns the Mailer extending and decorating class:

PHP Code:

<?php

namespace XLite\Module\XCExample\EmailDemo\Core;

/**
 * Mailer core class
 */
abstract class Mailer extends \XLite\Core\Mailer implements \XLite\Base\IDecorator
{
    public static function sendEmailDemoMessage($to, $body = '')
    {
        static::register([
            'subject' => 'Demo notification',        
            'body' => $body,
        ]);

        static::compose(
            'DemoMail',
            static::getSiteAdministratorMail(),
            $to,
            'modules/XCExample/EmailDemo/message',
            array(),
            true,
            \XLite::CUSTOMER_INTERFACE
        );

        return static::getMailer()->getLastError();
    }
}

Would there be another method substituting register() method for 5.4.x, or the related code is different in other places as well, compared to the code presented in the article?
