title: Inherited vs local MIME type
body: <p>I am trying to add a MIME type. 
  After adding it, the browser does not recognize the type.
  When I compare it to the demo that works, the only difference that I can see is that in the demo the Entry type is inherited and the one I produce Is Local.
  Could anyone explain the difference (I was unable to find anything about it on google).
  How do I produce inherited MIME type? (on the demo is was just created that way, but on the beta site it is create as Local!?!)
  BTW, in both demo and beta site it is version 6.1.</p>
  
  <p>Thank you very much</p>
