Assembly: System.Xml (in system.xml.dll)
When serializing or deserializing an object, the XmlSerializer class does not do XML validation. For this purpose, it is safe to provide a trivial implementation of this method, for example by returning a null reference (Nothing in Visual Basic).
This method is called by the WebServiceUtil.exe utility when generating a proxy for your class to be consumed by a Web service client. For this purpose, it is essential that the method return an accurate XML schema that describes the XML representation of your object generated by the WriteXml method.
