Re: The concept of cascading

All of this discussion I think ignores the fact that style sheets make
it much easier for authors to offer different versions of a document,
simply by attaching a different style sheet. Authors who are offering
content-driven material for a general public that may include various
physical/technological handicaps, it seems to me, should have a
responsibility to post design-simple versions. Perhaps we should be
looking at a way to standardize and tag these simple versions so that
UAs written for special needs can automatically find them.
