Minutes

innerHTML/document.write

RS: Andi Snow-Weaver says not required, bad requirement

Group: ...no support until told otherwise

use of <b>, <strong>, etc.

JG: should apply to any styling via inner tags (e.g. <em>, <strong>, etc.)

squillace: ...use should result in a violation

JonGund: * The font and center elements must not be used. Instead use structural markup with CSS for styling.

JonGund: * The b element must not be used for bold styling of text content. Instead use heading elements h1..h6 for heading text or the strong element for emphasizing words, phrases or sentences.

JonGund: * The i element must not be used to italicize text content. Instead use heading elements h1..h6 for heading text or the em element for emphasizing words, phrases or sentences.

JonGund: * The u element must not be used to underline text content. Instead use heading elements h1..h6 for heading text or the em or strong elements for emphasizing words, phrases or sentences.

JonGund: * The blink and marquee elements must not be used.

JonGund: Blinking or moving text causes accessibility problems for people with photosensitive epilepsy and visual impairments.

Event handlers

RS: rule: generate violation when only pointing/jouse-oriented event handlers present

JG: finding event handlers in and of itself is expensive

DT: http://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/F54

JG: actual WCAG2 criterion seems to indicate pointing device-speicific handlers for script functions, not nodes

VO: RPT looks for particular onmouseXXX/onXXX pairings (e.g. onmouseover, onfocus or onmouseout => onblur)

VO: ...wiki updated with full set of pairs; error generated when one of pair is missing

RS: what if a container element is managing sub-controls (e.g. grid)? How is this algorithm effected?

JG: find event handlers and at least one parent supports onkeyXXX or simulate keystroke into widget and see if it is consumed by it

squillace: ...other issues is just being able to enumerate the handlers; most of them are added in the script code

ACTION: JG to update event handler section due 04/22/2009
