This type contains a collection of XmlAttributes objects, which are used to customize the way the XmlSerializer serializes an object to XML. Its Add( ) method has two overrides, one that takes a System.Type indicating the type of object it applies to and the XmlAttribute instance containing the attributes, and one that takes those two parameters plus a System.String containing the name of the member of the type to which the attributes apply.

The XmlAttributeOverrides instance is passed to the XmlSerializer constructor to create the serializer with the overriden attributes.
