The author-driven evolution of DTDs will provide many good architectural ideas. Even so, architects will have finer control, and more control, over the output of document authors than ever before. Many new kinds of document validation will appear. HyTime already provides some very general ones. Architects can use these validation features to insure a quality product.
Authors can use architecture-provided validation features as writing aids.
For example, using HyTime, by adding a lextype attribute. Managers don't have to be programmers to understand it. Given the right tools, managers don't have to be programmers to USE it, either. Tools for supporting the tweaking of DTDs in conformance with their base architectures are needed, so that architects can let authors follow their consciences, without worrying about the consequences. Adapt or die.
