Below is some related information on a diagram and document to explain
the relationship between WCAG2 documents and the design of the user
interaction between the docments. What Sailesh sent to the list can
inform a WCAG intro page, explained below.

As part of the WAI site redesign[1], we determined the need for
introduction pages to provide high-level info for WCAG and other
areas.[2] A few motivations for these are:
- People have difficulty understanding the relationship between the
current WCAG 1 guidelines and techniques documents. (e.g., a usability
testing participant who rated herself as expert in accessibility did not
have a clear concept of the documents, and often when I've showed a
simple diagram of the relationship in a presentation, I get "oh! now I
get it!" reactions)
- Usability testing confirmed that people were overwhelmed, confused,
and turned-off by the front matter of /TR/ docs (this version, latest
version, previous version, editors, copyright, abstract, status of this
document... "finally I find the contents") and the number of different
documents. They did not recognize when the moved from one document to
another, e.g., when follow link from guidelines to techniques. They got
lost, not knowing where they were or how to get back to where they had
been before.

For WCAG1.0, the simple diagram I show has "WCAG 1.0" with an arrow
pointing to "Techniques Gateway" and from there 3 arrows to "Core
Techniques", "HTML Techniques", "CSS Techniques" -- just that simple
thing made a lot of difference to people, because they had not been able
to figure out the different documents and their relationships-
especially confusing seems to be when they clicked on techniques they
expected to get some real content, and were baffled by being in the
middle of what is just links (the gareway without content).

Per the discussion in the techniques teleconferences the last two weeks,
I think we need something like that for WCAG2 -- for later to help
explain to users, and for now to help with development and design.

Additional notes (on ideas, not necessarily consensus!) from this week's
Question: Do we want people to read the general before the
Answer: Yes. Primarily want to encourage people to read the general
before they read the technology-specific. At the same time, also want it
to be easy for experienced people to skip the general and go right to a

How that might inform design:
- guidelines doc links to general techniques doc
- general techniques doc shows the general info, and makes it easy for
user to skip the text and jump to technology-specific techniques (e.g.,
user doesn't have to scroll through text to get to links)
- technology-specific techniques have clear link to the related general
info (for those who somehow get to the technology-specific without
having seen the general)
- traffic cop might be a shortcut interface for experienced users, but
not in the main flow
