title: Model validation with NancyFX
body: <p>I'm really get used with ASP.NET MVC approach: annotate model with corresponding attributes, MVC does validate it and updates ModelState.Errors, ModelState is available on View, so it is possible to show errors to user.</p>
  
  <p>I haven't found information on <a href="https://github.com/NancyFx/Nancy/wiki/_pages">wiki</a> how exactly it should be done for NancyFX. In <a href="https://github.com/NancyFx/Nancy/tree/master/src/Nancy/Validation/Rules">sources</a> I can see that Nancy trying to use Rules, but how to apply correctly and show failures on Views?  </p>
  
  <p><strong>EDIT</strong>: Question is relevant to Nancy 0.9, according to @TheCodeJunkie 0.10 will apply changes for that.</p>
