Documentation about NOT IN or <> ALL seems to be wrong

The ALL or ANY operators like presented in the documentation http://www.doctrine-project.org/documentation/manual/1_2/en/dql-doctrine-query-language#conditional-expressions:all-and-any-expressions seems to be not working.

I'm trying to use them but no way, I always get errors. For exemple if I do this query:

Doctrine_Query::create()
->from('Contact')
->where('Contact.id <> ALL (FROM Email(contact_id)')
->execute();

I get this error:
PHP Fatal error: Uncaught exception 'Doctrine_Exception' with message 'Couldn't find class Email(contact_id)'

Is there a problem in the documentation??
