Hello, > Looking at the Class Status page I cannot see any reference to > XmlDataDocument. What is its status? It's supposed to be part of > System.Xml.XmlDocument. I'm I just being obtuse? XmlDataDocument is placed in System.Data.dll, since it is ADO.NET class. You can find it here: http://www.go-mono.com/class-status-System.Data.html Cheers, Atsushi Eno
