XmlSerializationContext Class
The XmlSerializationContext class controls the way in which XML is serialized and de-serialized. It allows aspects of the validation to be changed, and the contents of the generated XML to be controlled.
If you not explicitly create an XmlSerializationContext object and pass it to the ToXML and FromXml functions, then a static instance of a XmlSerializationContext is used (accessible via XmlSerializationContext.Default).
