Occurs when the XmlSerializer encounters an XML attribute of unknown type during deserialization.
Assembly: System.Xml (in System.Xml.dll)
If the instance of the class being deserialized contains a field that returns an array of XmlAttribute objects and an XmlAnyAttributeAttribute has been applied to the field, the event does not occur. Instead, all unknown XML attributes are collected into the array.
