      'translation.class_path' => __DIR__ . '/../vendor/symfony/src',
      'translator.messages' => array('sr_Latn' => __DIR__ .'/../vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/translations/validators.sr_Latn.xlf')

Answer 1

You need to add a call to Translator::addResource:

$file = __DIR__ .'/../vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/translations/validators.sr_Latn.xlf';
$app['translator']->addResource('xliff', $file, 'sr_Latn', 'validators');
