   //Add the new node to the document.
   XmlElement^ root = doc->DocumentElement;
   doc->InsertBefore( newComment, root );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );

このメソッドでは、ドキュメントのコンテキストで新しいオブジェクトが作成されますが、新しいオブジェクトがドキュメントツリーに自動的に追加されることはありません。Although this method creates the new object in the context of the document, it does not automatically add the new object to the document tree. 新しいオブジェクトを追加するには、ノードの挿入メソッドの1つを明示的に呼び出す必要があります。To add the new object, you must explicitly call one of the node insert methods.

W3C拡張マークアップ言語 (XML) 1.0 の推奨事項に従って、entityreference ノードが属性ノードの子でない場合、Comment ノードは Document、Element、および entityreference ノード内でのみ許可されます。According to the W3C Extensible Markup Language (XML) 1.0 recommendation, Comment nodes are only allowed within Document, Element and EntityReference nodes, when the EntityReference node is not a child of an Attribute node.
