The .NET framework allows you to create an XML fragment by setting
   settings.ConformanceLevel = ConformanceLevel.Fragment;
on your XmlWriterSettings variable. That way you should be able to write 
out serveral DecoratedPerson elements. You should however be aware that 
you can't read the generated XML with XmlDocument or XDocument as these 
implement the W3C specification for well-formed XML documents to have 
exactly one root element that contains all other elements.
XmlReader on the other hand can also be set in "fragment mode" with an 
XmlReaderSettings instance and the same ConformanceLevel setting.
