I know :-)
Maybe We should ask @WouterJ if Name and Namespace is correct for that. He does not really like the phpcr-odm (caused by the code), but when doing some new We should do it right. 

Thought to extend from EventManager but then i saw, that there can be different event managers. But normally that behavior should be pushed to Doctrine\Common i think. But as i can't find any EventMangerInterface i should stop suggesting for doctrine :-), else i won't ever stop.
