Â /Roger I suggest it's an iterative process: Start with something simple that mostly does the job. As additional needs crop up, add the additional complexity to handle these needs. When you have something complex that really does the job, look at it and extract the simple elegant version that still really does the job. (optional) Expand the job and loop. I've seen it claimed that it takes about 40 years for a technology to loop. (or become a commodity if the job doesn't expand.) The classic example is aircraft, 40 years from World War I when they first became useful, to the 707. Markup seems roughly on track, from circa 1960 to xml with the bugs worked out circa 2000. The task has now expanded from document maintenance and presentation to more general information interchange, possibly without a human in the loop. We're in the complexification stage again, 15 years from SGML-TNG, thirty from xml-tng. Frank
