Maybe I misread some part of the documentation or don't know C# well 
enough but some functions and properties don't seem to be overridable. For 
example XElement.Add 
(http://msdn.microsoft.com/en-us/library/bb354061.aspx). Also for example 
XDocument.Load is static rather then virtual so to construct my own classes 
during loading XML I would have to provide in XMyDocument a function MyLoad 
for example.
    Or are there any examples of inheriting from X* classes?
