Re: UAWG Action item: Add title text to draft idea for splitting up the checkpoints.

BTW Although I have given my two cents on how UAAG might break into just 
4 categories I would like to remind people of the 2x4-part split that I 
suggested a while back.
(http://lists.w3.org/Archives/Public/w3c-wai-ua/2006OctDec/0053.html)

PART A: Make the user agent user interface accessible. [ie. "Chrome"]
  A.1: User agent user interface must be perceivable
  A.2: User agent user interface must be operable
  A.3: User agent user interface must be understandable
  A.4: User agent user interface must be access system friendly

PART B: Enhance the accessibility of rendered content.
  B.1: Perceivability of rendered content must be enhanced
  B.2: Operability of rendered content must be enhanced.
  B.3: Understandability of rendered content must be enhanced.
  B.4: Access system friendliness of rendered content must be enhanced.

I think this would help clarify what requirements the "Chrome" has to 
meet vs. what the user interface can do about the content it renders. I 
also wonder whether this goes some way towards what Al was advocating, 
though I realize the term "perceivable" remains (so I have CC'd him).

Thoughts?

Cheers,
Jan
