//
// NOTES:
//  Where possible, these tests avoid testing the order of
//  an object's members serialization. Mono and .NET do not
//  reflect members in the same order.
//
//  Only serializations tests so far, no deserialization.
//
// FIXME
//  test XmlArrayAttribute
//  test XmlArrayItemAttribute
//  test serialization of decimal type
//  test serialization of Guid type
//  test XmlNode serialization with and without modifying attributes.
//  test deserialization
//  FIXMEs found in this file
