Hello Tyler: On Friday 24 October 2003 9:44 AM EDT, Tyler Close wrote: > please answer the original question: "How exactly does the > thing described by a schema differ from a data model?" This question has been brought up before on this list. It is names vs. contents vs. context. One person's date is not the same as another's. Probably the best way to explain it would be to present my challenge: "I can take your schema and write an XML document that will not meet your needs, rather my needs". If I were a nice guy, I might tell you what the document really means, as the schema will never tell you. This has been done over and over again in business computing, Just To Get The Job Done. Need to send new data fragments over an agreed upon protocol, but have no time to redo the schema, or the person that would do that is on vacation? Then it is time to find new meaning for old fields. If it is important enough, the schema can be updated at a later date. And so it goes... Regards, Ralph
