Performs custom XML deserialization for properties which have the CustomXmlSerializationAttribute. The xmlreader should be used to read the xml from. The reader is positioned on the StartElement of the property which has the name of the property. Check if the element is empty and if not, read till the reader is positioned on the EndElement of the property (which also has the same name). Your override has to set the property's value, using the descriptor's SetValue method.
