I think you mean "clarify what requirements the "Chrome" has to
meet vs. what the user agent can do about the content it renders."
I like the split between chorme and the UA rendering content, but I think
there should not be a distinction between perceivable and understandable.
It seems like anything that is perceivable through a UA rendering must also
be understandable, that is aid in the end user's comprehension. Only 12.2,
12.4, and 12.5 fit under understandable and not really under perceivable.
Also, I think 10.1 Associate table cells and headers (P1) belongs under
perceivable and understandable, not operable.,
10.4 Provide outline view (P2)belongs under perceivable and understandable,
but when the outline view is navigable, it also belongs under operable.
8.1 Implement accessibility features (P1) fits under perceivable and
understandable - it goes hand in hand with 2.1 Render content according to
specification (P1, which is already under perceivable.
Should 8.2 Conform to specifications (P2) be converted into a baseline
statement for UAAG instead of being a single UAAG guideline?

Re: UAWG Action item: Add title
05/11/2007 02:54 text to draft idea for splitting
PM 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
