title: Disable validation on certain fields
body: <p>I've got a ViewModel for adding a user with properties: Email, Password, ConfirmPassword with Required attribute on all properties. When editing a user I want the Password and ConfirmPassword properties not to be required.</p>
  
  <p>Is there a way to disable validation for certain properties in different controller actions, or is it just best to create a seperate EditViewModel?</p>
