//       Class : XFileDataNode
// Description : This is an abstract base class for an XFileNode which
//               is also an XFileDataObject.  That is to say, objects
//               that inherit from this class may be added to the
//               toplevel X file graph as nodes, and they also may be
//               containers for data elements.
//
//               Specifically, this is the base class of both
//               XFileDataNodeTemplate and XFileDataNodeReference.
