Re: UAAG2: 10.2 Rewording ideas

REVISED AFTER JAN 31 CALL

Please note:
1. I've moved back closer to the sense of the previous wording
2. After thinking about it, I think except "(when "recognized" as 
"content-controlled")" can better be handled in the definition of 
content focus.


10.2 Highlight selection, content focus, enabled elements, visited links

Level A

1. Highlighting options are provided for the following classes of 
information:
(a) selection
(b) content focus
(c) enabled elements
(d) recently visited links.

2. The highlighting options include both of the following:
(a) foreground colors (with the same configurable range as the 
platform's conventional color selection utility)
(b) background colors (with the same configurable range as the 
platform's conventional color selection utility)

2. The highlighting options includes at least one of the following:
(a) borders (with configurable color and width)
(b) text size (with the configurable range required for checkpoint 4.1)

Level AA

(what about a AA requirement for a user command to animate or otherwise 
highlight where the content focus currently is?)

Level AAA
