title: HTTP PATCH method. Content in the request body
body: <p>I'm developping a REST API using Symfony2. I have a reservation system and I would like to send an email to a customer when his reservation is validate by an admin.</p>
  
  <p>I have a Reservation ressource, and we can validate a reservation using this url :</p>
  
  <p>PATCH localhost/:id/validate</p>
  
  <p>I want to know if is it correct to put the email content into the request body when validate a ressource, using the PATCH method.</p>
  
  <p>If no, what should be the correct way ?</p>
  
  <p>Thanks,
  Mehdi.</p>
