Default resource for data annotations in ASP.NET MVC

There's a way to set the default resource to the data annotations validations?

I don't wanna make something like this:

[Required(ErrorMessage="Name required.", ErrorMessageResourceType=typeof(CustomDataAnnotationsResources)]
public string Name { get; set; }

I would like something like this:

Global.asax

DataAnnotations.DefaultResources = typeof(CustomDataAnnotationsResources);

then

[Required]
public string Name { get; set; }

someone gimme a light!

thanks in advance

EDIT

My real problem was with EF Code First CTP4. CTP5 fix it. Thanks for everyone.
