C# Override an attribute in a subclass

public class MyWebControl {

    [ExternallyVisible]
    public string StyleString {get;set;}

}

public class SmarterWebControl : MyWebControl {

    [ExternallyVisible]
    public string CssName{get;set;}

    new public string StyleString {get;set;} //Doesn't work

}

Is it possible to remove the attribute in the subclass? I do want the attribute to get inherited by other subclasses, just not this one.

Edit: Whoops, looks like I forgot to compile or something because the code as posted above does, in fact, work!
