title: Nhibernate Extension points
body: <p>I'm looking for more information on the extension points within NHibernate. </p>
  
  <p>For instance I know about IUserType and ICacheProvider. However I can't seem to find a good reference of all the different extension points that NHibernate provides?</p>
  
  <p>Is anyone's Google-fu stronger than mine :)</p>
