The type of annotations to remove.

The following example creates an element with four annotations on it. It then uses this method to remove two of them.

public class MyAnnotation {
    private string tag;
    public string Tag {get{return tag;} set{tag=value;}}
    public MyAnnotation(string tag) {
        this.tag = tag;
    }
}

class Program {
    static void Main(string[] args) {   
        XElement root = new XElement("Root", "content");
        root.AddAnnotation(new MyAnnotation("T1"));
        root.AddAnnotation(new MyAnnotation("T2"));
        root.AddAnnotation("abc");
        root.AddAnnotation("def");

        Console.WriteLine("Count before removing: {0}", root.Annotations<object>().Count());
        root.RemoveAnnotations<MyAnnotation>();
        Console.WriteLine("Count after removing: {0}", root.Annotations<object>().Count());
    }
}

This example produces the following output:

Count before removing: 4
Count after removing: 2
