Disclaimer: I haven't read enough of the out-of-band communication on this topic that I can be sure I have understood all the relevant arguments and that this hasn't already been discussed somewhere. It seems like the case of an image as the sole content of a link might be special enough to warrant special consideration. In particular it seems that this is a case where, in the majority of cases, even auto-generated server side alt-text is likely to be better than auto-generated client-side alt-text since, at least in the case of internal links such as a photo album in which a image is a link to a larger version of itself, the server would have knowledge about the link destination. Possible suggestions: Significant (in the sense of both present and non-empty) @alt be required on images that are the sole contents of links. Presumably this should also be extended to cover other types of embedded content which have the possibility of textual fallback. In the case where such fallback content is missing but the link has a title attribute, the contents of that title attribute be used as the fallback content for the link. -- "Mixed up signals Bullet train People snuffed out in the brutal rain" --Conner Oberst
