They're abstract concepts.
Well, abstract ideas too. It seems that they are not making great
progress - the draft is _still_ very sketchy.
Worst of all, they are breaking continuity with WCAG 1.0, by making the
structure of the recommendation completely different. And WCAG 1.0 has
received widespread (and often too religious) acceptance - e.g., it has
been explicitly recommended by the European Parliament. Politicians and
authors alike will get confused if WCAG 2.0 ever becomes a W3C
recommendation.
I prefer the more hands-on HTML Techniques for WCAG 2.0,
<
http://www.w3.org/TR/WCAG20-HTML-TECHS/>.
Not much new there, as compared with the corresponding document for
WCAG 1.0. And actually it's getting worse. They now say we shouldn't use
title="..." for <img> and they still promote the clumsy and unimplemented
longdesc="..." idea.
But anyone who believes in the fundamental ideas of WCAG 2.0 should
probably comment on it on the mailing list mentioned in the draft - that
way the comments have a much better chance of getting notified than
comments on other fora.
