Witness the way a DTD grows like topsy. The system is never that neat because the requirements aren't. Good thing too. OTW, everything would have been built in the last century and we would all be steam engine repairmen. I contend that topic maps, data types, and other ideas currently circulating happen because we need them. Sort of a Duh, but again, it points to the need to get requirements prior to design. I spent the day creating a DTD for a language in which the original grammar has very explicitly defined datatypes. I stuck CDATA everywhere and am not very about that. Of the various datatype proposals out there: 1. Which is most legitimate to apply today? 2. Which is likely to survive into XML1.>0? I can use a stopgap if it has credibility.
