Re: character limit on alt attribute for screen readers

A major problem with Alt text is the fact that it is not structured content. This has to be taken into account, as a user of assistive technology could not easily navigate within larger amounts of Alt text. There is a reason we require good content structuring everywhere else, and as structuring can't be done inside an Alt text the text has to be kept reasonably succinct.
