title: Doctrine2 entities in multiple namespaces
body: <p>I'm developing a web application using Zend Framework 2 which will be made of several modules, and I'd like to put the entity classes in the module to which they belong.</p>
  
  <p>Is it possible to do this using Doctrine2 ORM? By reading the docs, it seems to always expect to have all the entities under at most one namespace, while I'd like to have</p>
  
  <ul>
  <li>Module1\Entity</li>
  <li>Module2\Entity</li>
  <li>and so on...</li>
  </ul>
  
  <p>How could this be made possible?</p>
  
  <p>Thanks to all!</p>
