XElement root = new XElement("Root", "content");
root.AddAnnotation(new MyAnnotation("T1"));
root.AddAnnotation(new MyAnnotation("T2"));
root.AddAnnotation("abc");
root.AddAnnotation("def");

IEnumerable<MyAnnotation> annotationList;
annotationList = root.Annotations<MyAnnotation>();
foreach (MyAnnotation ma in annotationList)
    output.Append(ma.Tag + Environment.NewLine);
output.Append("----" + Environment.NewLine);

IEnumerable<string> stringAnnotationList;
stringAnnotationList = root.Annotations<string>();
foreach (string str in stringAnnotationList)
    output.Append(str  + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
