XMLDOMDocumentFragment Object
The XMLDOMDocumentFragment object will be used to create fragments of documents that can be appended to another document. When the XMLDOMDocumentFragment object is inserted into a document object, the root node of the XMLDOMDocumentFragment is not inserted, only its children. Thus, XMLDOMDocumentFragment objects are useful for inserting child elements into a document.
The XMLDOMDocumentFragment object implements the IXMLDOMDocumentFragment interface. This interface inherits all the IXMLDOMNode interface's methods and properties, but it doesn't extend the interface, so this interface has no additional methods or properties of its own.
