Given that "photo sharing" is one of the most popular activities on the internet, all the more reason to not leave open the door that suggests that sometimes an image without @alt is "conformant". The constant refrain from the working group is that this would be a rare instance, yet you now suggest that it will be the majority, and not a rare instance at all. If 10 of the top 100 websites on the WWW have this magic get-out-of-jail-free card then surely others will seek to claim the same status. The precedent being suggested here is staggering.

Exactly!! What unintended consequences and second-order effects do you think will emerge once you make @alt optional for a class of sites that claim "special status"? One possible outcome will be that more sites will seek to claim this status, and the overall quantity of images with @alt will diminish. This is a real possible outcome, and to suggest otherwise is simply disingenuous. More and more, we are seeing a new way of "publishing" to the web that removes any actual "coding" by the content author: CMS tools such as Drupal and Joomla (which have embedded editors such as Tiny MCE or FKCEditor), wikis and their kin, and social networking sites such as MySpace and Facebook. If all of these "sites" and authoring methods get to claim "special" status because they have the author upload images (be it 1, or 3,000 vacation photos), where goes accessibility, and how exactly is this a benefit? > Several ways to mark in image in such a manner have been proposed.

You also left out the possibility of reserved values for @alt, or my suggestion that should an <img> have one of a possible many means of directly associating a textual equivalent to an image that conformance could be considered - if @alt is not the best solution in a given scenario, is there a different solution that could/would work besides just saying "leave out the @alt"? Once the WG comes to the conclusion that optional @alt as proposed is a non-starter and starts really discussing a different approach, this debate will continue to churn and go round-and-round 'till the cows come home. There have been many off-line comments within the working group about "dogma" emerging from the accessibility camp, but the responses from the other side are equally immobile and dogmatic - simply stating that <img src=""> will improve accessibility will not make it true, no matter how many times you say it. > > They are relevant to whether the use case of embedding images where > alternative content is not available is important to consider. If you > agree that it is, then I agree there is no need to debate the matter. In this there is total agreement. The current proposed method is not acceptable, let's agree to that and start real dialogue on a better way forward shall we? JF
