title: EF -> RIA Services -> Silverlight, Can I show validation error messages but still Save changes
body: <p>I am using Entity Framework 4.0, RIA Services, and Silverlight 4.0.  I need the user to be able to save any changes regardless if they are correct or incomplete.  To do this I had to make a lot of fields in the database nullable.  I still want to be able to show validation error messages in the Silverlight client to the user.  What I would like to do is use DataAnnotations to attribute the entities metadata in Ria Services to get the nice validation error messages on the client but I need the user to be able to save even if it breaks validation.  Is this possible?  How would I go about implementing this?</p>
  
  <p>Thanks,
  Evan</p>
