I can understand that if you were starting with the xml you would not know which format of xml to create when converting back from the object you created and that therefore you could end up with a different XML structure to that which you started with. But if you were starting off from the object, would it not be feasible to have a conversion routine that always adopted the same approach when converting from an object to the xml data. Thus making it possible to consistently convert from the object to the xml and back again? (I know I am talking theoretically here - how you would achieve it I am not currently sure).</p>
