that alt remain what it was intended to be - a REQUIRED terse textual equivalent for static images, in accordance with the usage guidance provided by WCAG, ATAG, and UAAG, and in line with the alt inherited from HTML 4.01. that a role or type attribute be added to the IMG element's collection of attributes, which would provide the sort of generic information that the current draft of HTML5 specifies should be contained in curly brackets as the value for alt - for example:. the "curly brackets" verbiage concerning alt be removed from the HTML5 draft. Therefore, i would like PF to FORMALLY propose to the HTML WG that: Not only is the "curly bracket" technique insufficient, it constitutes both an abuse of the alt attribute and does not satisfy the WCAG requirement that alt text contains a textual equivalent of the image. Recently, the "curly brackets" hack of identifying a graphical image by its use or type by inserting a generic identifier / descriptor in curly braces as the value for an IMG, has been added to the HTML5 working draft.
