Poll: Attribute Design

I would like to run a quick poll. Which design do you prefer for a set of related attributes and why?

Option #1: Several Attribute Types:

public class AaaaFooAttribute: Attribute { }

public class BbbbFooAttribute: Attribute { }

public class CcccFooAttribute: Attribute { }

public class DdddFooAttribute: Attribute { }


Option #2: One Attribute Type and One Enum

public class FooAttribute: Attribute {

     public FooAttribute(FooType type) {}


public enum FooType { Aaaa, Bbbb, Cccc, Dddd }
