  Hi,

Here are a few problems with 3.5.2 that I noticed. 3.5.1 and 3.5.2 currently read:

    *3.5.1 Highlighted items:* The user has the option to highlight <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-highlight> the following classes of information so that each is uniquely distinguished. (Level A):

        * *(a) selection*,
        * *(b) content focus*,
        * *(c) recognized <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-recognize> enabled elements*, and
        * *(d) recently visited links*.

    *3.5.2 Highlighting options:* The highlighting options (with the same configurable range as the operating environment's <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-operating-environment> conventional selection utilities) include at least (Level A):

        * *(a) foreground colors*,
        * *(b) background colors*, and
        * *(c) input focus* (with configurable color and width).


1. In the SC 3.5.2 item C, the term "input focus" is incorrect; the Intent paragraph and example both discuss borders, which would make more sense and better fit the listed properties of "color and width", so list item (c) could be changed from "input focus (with configurable color and width)" to "border color and width". However, what software actually provides an optional, adjustable border for selection, content focus, enabled elements, visited links, etc. for both user agent user interface and rendered content? ("Text cursor" also has both color and width, but wouldn't really apply to most of the things to be highlighted.)

2. 3.5.2 only makes sense if you know it's supposed to be applied to 3.5.1. They could either be merged (as I seem to recall us discussing doing for another pair of closely related SC) or modified to refer to each other. The arguments for combining them would be that they're intimately tied, that as both are Level A to conform you have to do both anyway, and that it could simplify the wording if 3.5.2 doesn't have to refer back to 3.5.1; the arguments against are that you might want to check them off separately to keep track of partial progress towards full compliance, and to avoid having one success criterion with two lists.

The first approach is combine them:

    *3.5.1 Highlighted items:* The user has the option to highlight <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-highlight> the following classes of information so that each is uniquely distinguished:

        * *(a) selection*,
        * *(b) content focus*,
        * *(c) recognized <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-recognize> enabled elements*, and
        * *(d) recently visited links*.

    **The highlighting options (with the same configurable range as the operating environment's <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-operating-environment> conventional selection utilities) include at least (Level A):

        * *(a) foreground colors*,
        * *(b) background colors*, and
        * *(c) input focus* (with configurable color and width).


The second approach is to modify 3.5.2 to explicitly refer to 3.5.1 so you know what it's about, such as changing the beginning of 3.5.2 to read "When complying with 3.5.1, the highlighting options...", thus yielding:

    *3.5.1 Highlighted items:* The user has the option to highlight <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-highlight> the following classes of information so that each is uniquely distinguished. (Level A):

        * *(a) selection*,
        * *(b) content focus*,
        * *(c) recognized <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-recognize> enabled elements*, and
        * *(d) recently visited links*.

    *3.5.2 Highlighting options:* When complying with 3.5.1, the highlighting options (with the same configurable range as the operating environment's <http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-operating-environment> conventional selection utilities) include at least (Level A):

        * *(a) foreground colors*,
        * *(b) background colors*, and
        * *(c) input focus* (with configurable color and width).


     Thanks,
     Greg
