title: Is it possible to use 2 remote validation attributes on a single property?
body: <p>Is it possible to use 2 remote validation attributes on a single property in a view model?</p>
  
  <p>What I would like to be able to do is perform 2 checks, first that a given user id exists in the DB and second that the user has not already set up an account on the system.</p>
  
  <p>I guess I could always make a custom attribute which has both tests in it, but if possible I would prefer to just use the out of the box functionality and chain the validations together.</p>
  
  <p>I cant really combine the logic together into a single JsonResult, as I need to have different error messages depending on how the validation fails, and AFAIK its not possible to return the error message with the validation result?</p>
