RE: Prototype Silver SC

Hi Jim,

This has been on my mind, I think for the purpose of silver it would be good to pick one that is high on the user-benefit scale, and high on the difficulty scale as well, something over-lapping with user-agent issues.

Perhaps personalisation, but a specific example of that?

E.g. User can change the foreground and background colour of text content.

Printing is probably a similar scale, but I wasn’t sure which would be of more benefit.

Cheers,

-Alastair

Subject: Prototype Silver SC

Last week, the Silver Task Force asked the LVTF for SC that did not make it in to WCAG21. Several items were mentioned, see below. Which is our #1 choice

  *   Browser exemptions/issues

     *    1.4.11 [1] -  "... where the appearance of the component is determined by the user agent and not modified by the author;" the exemption for contrast of native active elements (form element, focus ring, media controls, etc.) failing WCAG20 3:1 contrast threshold
     *   1.4.13 [2] - "Exception: The visual presentation of the additional content is controlled by the user agent and is not modified by the author."  the exemption for 'title' attribute

  *   Element Level Customization [3] - user interface for UA to allow override of many values. Closely related to Personalization. It is the super set of the proposed SCs on font size, family, color, justification, hyphenation, etc. Also know as Return of User Stylesheets
  *   Printing [4] - documents printed do not loose content. Huge discussion - much having to do with testing. Closely related to this is the user being able to print what is on the screen after all of the font, spacing, and sizing changes have been applied. Would be nice not to have to write a print style sheet. If I zoom a page a bit to make it easier to read, I want to print at that size.
