how about the author's name and contact data. ----- Original Message ----- From: "Laura Carlson" <laura.lee.carlson@gmail.com> To: <Jutta.treviranus@utoronto.ca>; <jimallan@tsbvi.edu>; <jan.richards@utoronto.ca>; <shadi@w3.org>; <Alfred.S.Gilman@ieee.org>; <wai-xtech@w3.org>; <wai-liaison@w3.org>; <cooper@w3.org> Cc: <public-html@w3.org> Sent: Tuesday, April 15, 2008 1:47 PM Subject: Request for review of alt and alt value for authoring or publishing tools As PFWG is aware [1], the HTML 5 working group is questioning and debating the need for the alt attribute on "critical content". In particular one case in the HTML 5 Draft states: "In certain rare cases, the image is simply a critical part of the content, and there might even be no alternative text available. This could be the case, for instance, in a photo gallery, where a user has uploaded 3000 photos from a vacation trip, without providing any descriptions of the images. The images are the whole point of the pages containing them. In such cases, the alt attribute may be omitted, but the alt attribute should be included, with a useful value, if at all possible. If an image is a key part of the content, the alt attribute must not be specified with an empty value." All of the following have been discussed as potential solutions to this issue. Our question is, what should an authoring or publishing tool insert, in a case where no alt has been provided by the author, but the image is known to be "critical content"? a. No alt attribute provided as stated in the current draft <img src="vexed.jpg"> b. An alt attribute with some type of standardized reserved value to indicate that the image is "critical content" but the author has not supplied a text alternative. (example value for the purposes of illustration only) <img src="vexed.jpg" alt="?">or <img src="vexed.jpg" alt="_none"> c. An attribute separate from the alt that serves to indicate that the image is "critical content", but no text alternative has been provided. <img src="vexed.jpg" alt="" noalt> or <img src="vexed.jpg" noalt> d. A null alt <img src="vexed.jpg" alt=""> e.
