I just saw this JQuery Metadata Plugin by John Resig, Yehuda Katz, Jarn Zaefferer, and Paul McLanahan, in my search for JQuery Form Validation, and that's an interesting idea! I'm wondering what general best practices are for storing things like error/validation text, tooltip text, default value text, etc. I know you can place them int...

With the new ASP.NET MVC 2 validation features, we can decorate the properties of our domain model objects with DataAnnotations attributes that describe criteria for valid values.
