Additional Items For Last Call Review
- ISSUE-31 "alt-conformance-requirements" - affects Requirements for providing text to act as an alternative for images section of spec
- ISSUE-80 "title-alternative" - affects Requirements for providing text to act as an alternative for images section of spec - See also Request to Reconsider ISSUE-80 decision
- Bug 9216: Provide a CAPTCHA example that is in accord with WCAG 2 or Defer to "HTML5: Techniques for providing useful text alternatives" - Spec reference: Images whose contents are not known
- Bug 9215: Provide a Webcam example that is in accord with WCAG 2 or Defer to "HTML5: Techniques for providing useful text alternatives" - Spec reference: Images whose contents are not known
- ISSUE-131 "caret-location-API" - This API does not yet provide the ability to supply an assistive technology with the bounds of a drawing object on the physical canvas bound to canvas elements in the canvas subtree. To do this properly the specification needs to provide clickable canvas regions, representing the canvas element in the subtree. This would mean the inclusion of hit testing capability in canvas that would bind pointing device events retrieved from the canvas drawing surface to the canvas subtree. - affects canvas section of spec
- Bug 11239 Draw Focus - drawFocusRing needs to be separated into separate functions to separate the concept of focus rings and the drawing of visual points of regard for managed children. Also, a defect exists whereby an author can choose to use canDrawCustom when no system setting is provided for how the ring should be drawn and author will be allowed to draw a focus ring without driving a magnifier. (Note: this issue was raised with the chairs, the additional information was provided but not discussed) - affects Focus Management section of Canvas 2D API spec
- Bug 11342 Text Metric - A text baseline needs to be added to the textMetrics. (Note: the chairs asked for more clarification on what textMetrics were provided, the additional information was provided but not discussed). The revised text is provided in the updated change proposal. - affects Text section of Canvas 2D API spec, last paragraph referencing TextMetrics interface
- Media Navigation Strategy - See Content navigation by content structure requirements - Still undefined - affects The Video element section of spec

- Drag & Drop Requires Verification. We believe the spec is correct, but we have not verified because we lack an implementation to test with. No need to reference an issue in the spec.
