IDOMNode is the interface for this node provided by the DOM implementation that parsed the XML document. It can be accessed through the DOMNode property of the node's IXMLNode interface. 

Typically, applications that contain TXMLNode descendants use the IXMLNode interface to work with a node rather than the IDOMNode interface. IDOMNode is used more typically in applications that work directly with the DOM interfaces. 

The value of DOMNode is set to the IDOMNode interface that is provided to the TXMLNode constructor.
