https://www.w3.org/Bugs/Public/show_bug.cgi?id=20048 Bug ID: 20048 Summary: remove decorative image code example Classification: Unclassified Product: HTML WG Version: unspecified Hardware: PC OS: Windows NT Status: NEW Severity: normal Priority: P2 Component: HTML Image Description Extension Assignee: chaals@yandex-team.ru Reporter: faulkner.steve@gmail.com QA Contact: public-html-bugzilla@w3.org CC: public-html@w3.org There is disagreement over the decorative image example code in the spec: <img src="DecorativeImage" alt="" title="decorative image" longdesc="http://example.com/descs#item3"> It's is considered by at least one person that it conflicts with WCAG advice: http://lists.w3.org/Archives/Public/public-html-a11y/2012Nov/0107.html I would also make these other observations: 1. The HTML5 spec defines use of alt=”” to equal role=presentation so conforming user agents must implement alt=”” the same way as it., role=presentation which removes the img from the accessibility tree it also removes its title attribute content So this <img alt=”” title=”poot”> should not appear in the accessibility tree same as <img role=”presentation” title=”poot”> does not appear as implemented now. 2. Though the above is not implemented (so it appears in the acc tree) when an image has an alt=”” title text does not get announced in AT (tested in NVDA, but pretty sure it is the case for others) nor does the presence of the image. 3. Use of a title attribute in this case even if it was announced makes no semantic difference as the title is used as the accessible name for the image when an alt is not provided (example: <img title=”poot”>) 4. If the title attribute is used it is presumed that this information should be available to users other than AT users (who don’t get it anyway). It is well know that this is not the case as the title attribute in not device independent accessible as implemented in the vast majority of user agents. -- You are receiving this mail because: You are on the CC list for the bug.
