I see with the Castle validators I can use a length validation attribute.

    [ValidateLength(6, 30, "some error message")]
    public string SomeProperty { get; set; }

I am trying to find a MinLength only attribute is there a way to do this with the out of the box attributes?

So far my idea is implementing AbstractValidationAttribute

public class ValidateMinLengthAttribute : AbstractValidationAttribute

and making its Build method return a MinLengthValidator, then using ValidateMinLength on SomeProperty

public class MinLengthValidator : Castle.Components.Validator.IValidator

Does anyone have an example of a fully implemented IValidator or know where such documentation exists?? I am not sure what all the methods and properties are expecting.

Thanks
