Does ASP.Net MVC 2 validation need some more thought in terms of patterns and use?

Question

Here is the lay of the land. Like most people I have my domain object and I have my view models. I love the idea of using view models, as it allows for models to be created spec

Answer 1

The DataAnnotation attributes are about validating input and giving UI feedback to the end user. That's really their only intended use. I use different validation strategies for UI objects and business objects, so the DA validation attributes only end up on models being shown to the user.
