I think it is because XML has its own format and standards that has to be observed and exceptions need to be raised when it doesn't meet those formats/standard. But they could have at least added one more overloaded method that excepts XML string as an argument, doing the same thing we are doing behind the scene. May be it's on its way in the next release of the .NET framework...
