add data annotations programmatically

Question

I am working on an asp mvc3 app that is using .NET 4.

However the model I want to use is in a class library that is using .NET 3.5 and cannot change.

Can I add the .NET 4 data annotations to some properties in my model in the controller programatically to get some easy validation?
