I'm in early phase of building a RIA with ExtJS and ASP.NET MVC. Users in the system will have numerous different user rights that restrict which elements are visible and what actions user can make.

What does the castle validators offer me over standard data annotations?

Usually, these are reported via e-mail using ELMAH (using this setup), but since this was a compilation issue (of some sort), it did not get reported via e-mail.

Hello, I made a new action filter (attribute, similar to [Authorize]) which authorizes access to a controller action based on a session value. However, I'm basically decorating all my controller actions with that attribute (with the exception of very few). So, I thought it would be better to have that Action Filter always executed exc...
