[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: The general XML processing problem
 AKA, "XML separates content from presentation" and people insist that is true when it isn't. XML enables that and one does it because that makes the data portable. Then there is the "XML makes data interoperable" and that isn't true either and in fact, XML can't do anything about that at all. We can go round and round and round this age old topic of markup. Past the parse, every process and process definition, interaction, forging, hiding, dealing, and ... is all up for grabs. But that essentially defeats the notion of blind interoperability. The truth is, the web has NEVER provided that and I can't conceive of a system doing any useful work that does. It simply comes down to how much one can afford or afford not to see. That is a system definition. HTML worked because it was fixed. When it quit being fixed and started being extended, browsers failed. When complicated extensions were made, if the specifications for the extensions were ambiguous, content failed. How much and how complicated a definition becomes depends on how hard the task is and how many non-local processors have to do it exactly the same way to get the same results. No free lunch for Schrodinger's Cat. Invisibility cloaks are no guarantee one won't get stepped on. Some people do need to declare intent and type a priori. That's bad for those who depend on invisibility cloaks to get things done. It won't ruin the web to have others doing complicated things; it will make it expensive to do those things the first time and every time they hit a new requirement. It will make it expensive for anyone to get in the game after the first few do. A complex web depends on the Cat having Deep Pockets. I read that NPR owes the web an apology. Precisely who would that be delivered to? If someone commits a crime to the commons, who collects restitution? len -----Original Message----- From: Simon St.Laurent [mailto:simonstl@s...] What's interesting to me about this discussion is the separation of the information in the XML document from the processing it will receive. Although the creators and senders of that document may have their own expectations about how that document will be processed, there is nothing intrinsic to the XML which binds it to particular processing.
