Since those originators admit that it isn't a universal format, that would eliminate it as an alternative to an RM, without even considering the other omissions. As for representation, that word suggests some agreement as to context/subject, so I would say it's not even a machine representation but rather a way record some agreed-upon tree and nothing more. If the xml people stepped up to the plate, they would need to specify its operations, which I suspect would be as idiosyncratic as those of IMS,IDS,IDMS etc. Instead they cop out with: "A program can then recognize this document as a customer order and do whatever it needs to do: display it one way or display it a different way or put it through a bookkeeping system or make a new shirt show up on your doorstep tomorrow." Ie., basically the anthropo-phrase, "whatever it needs to do" is valley-girl talk - the XML operations are "whatever!".
(Also, regarding data transmission, it's a pretty fat format.) Received on Mon Aug 10 2009 - 15:02:07 CDT
