Can we update the comment to briefly describe what |InsertReplacementText| does?
e.g. Spellcheck, auto-correct or similar.

   enum DataTransferType {
     CopyAndPaste,
     DragAndDrop,
+    InsertReplacementText,
   };
 
   static DataTransfer* create(DataTransferType,
                               DataTransferAccessPolicy,
                               DataObject*);
   ~DataTransfer();
 
   bool isForCopyAndPaste() const { return m_transferType == CopyAndPaste; }
   bool isForDragAndDrop() const { return m_transferType == DragAndDrop; }
