Doctrine ORM mappings pass file missing

[youlweb]

I installed Symfony 2.5 fresh using composer create-project symfony/framework-standard-edition path/ "2.5.*".
Now I'm trying to follow the instructions on how to provide model classes for several Doctrine implementations (http://symfony.com/doc/current/cookbook/doctrine/mapping_model_classes.html). Great article btw, thanks for providing such advanced maneuvers in the doc. Unfortunately the dependency Doctrine\Bundle\DoctrineBundle\DependencyInjection\Compiler\DoctrineOrmMappingsPass is not present on my system. In the instructions page, the blue box labeled "2.3" mentions that the file should be included in Doctrine-bundle >= 1.2.1. My composer.json says: "doctrine/doctrine-bundle": "~1.2", which should definitely match that requirement.
I downloaded Symfony 2.5 in .zip version to double check, and the file is missing there too.
Any help appreciated.

The description in the Symfony cookbook is actually wrong. The DoctrineOrmMappingsPass class was first part of DoctrineBundle 1.3.0-beta1. I created an issue on the documentation repository for this (see symfony/symfony-docs#4273).

Thank you @youlweb for spotting this!
