Re: Intro to WCAG 2.0 [was Re: [Fwd: A Call to Reorganize WCAG 2.0]]

Shawn,
Some comments folow:
1. Prefix the word principles with "accessibility" or say principles of accessibility. 

Advise  WCAG-WG too to incorporate this  terminology in WCAG 2.
2. Need to highlight that the three-priorities  system under WCAG 1.0   used to categorize 
checkpoints was meant to signal  issues which in the view of the WCAG-WG, were vital / 
essential / desirable for  ensuring accessibility.
On the other hand, the levels used to categorize success criteria in WCAG 2 are suggestive 
of the method a content-author may adopt in order to adhere to a guideline.  Level 1 for 
instance suggests dependence only on mark-up that is interpretable by the browser and 
assistive technology to incorporate basic accessibility. Level 2 also includes   direct 
changes to content and/or presentation to enhance accessibility. 
Admittedly, WCAG 2 doc acknowledges that the conformance definitions are not yet set in 
stone and the introduction section here  needs to reflect that for now. But I think that the 
priorities and levels signal an important distinction between the two docs  that should find 
mention in the intro. One should not be  left to figure it out by reading the requirements 
doc (if it is mentioned there).
3. Need to  put the docs in perspective: say that WCAG 1.0 was the result of the first  effort to define Web accessibility ghguidelines.  This  was in the late nineties when HTML was the  dominant technology for authoring Web  content. WCAG 2 is the result of the 
- learning that has taken place since WCAG 1, 
- considers developments in user agents and adaptive technologies and 
- considers other W3C technologies that have since evolved and matured like XHTML, CSS, XML, SVG, etc

4. I feel that the words priority and level  in the two statements below are not required.
"The basis for determining conformance to WCAG 1.0 are the _priority_ checkpoints."
"The basis for determining conformance to WCAG 2.0 WD are the _level_ success criteria."
