Symfony2: How to use validators of a different Bundle

Question

I'm trying to use the validators of FOSUserBundle in my own form, but I don't know how to set up the validator.yml. It currently looks like this:

Acme\UserBundle\Entity\User:
    constraints:
        - FOS\UserBundle\Validator\Unique:
            property: usernameCanonical
        - FOS\UserBundle\Validator\Unique:
            property: emailCanonical
    properties:
        username:
            - NotBlank: ~
        email:
            - Email: ~
            - NotBlank: ~
        mandant:
            - NotBlank: ~
            - Type: Acme\UserBundle\Entity\Mandant

But this results in the following PHP error:

[05-Mar-2012 14:47:56 UTC] PHP Stack trace:
[05-Mar-2012 14:47:56 UTC] PHP   1. {main}() W:\redacted\symfony_webfrontend\app\console:0
[05-Mar-2012 14:48:10 UTC] PHP Fatal error:  Class 'FOS\UserBundle\ValidatorUnique' not found in W:\redacted\symfony_webfrontend\vendor\symfony\src\Symfony\Component\Validator\Mapping\Loader\FileLoader.php on line 73

It looks like the class path is wrong but I can't find any documentation on how to use validators of a different bundle in my own validators.yml...

Not sure why it actually works now because I tried this before, but this seems the way to go:

namespaces:
    FOSUserBundle: FOS\UserBundle\Validator\

Acme\UserBundle\Entity\User:
    constraints:
        - "FOSUserBundle:Unique":
            property: usernameCanonical
        - "FOSUserBundle:Unique":
            property: emailCanonical
    properties:
        username:
            - NotBlank: ~
        email:
            - Email: ~
            - NotBlank: ~
        Mandant:
            - NotBlank: ~
            - Type: Acme\UserBundle\Entity\Mandant
