Hi Leif, > only because graphical UAs don't search or copy the fallback. Yes. The thing is that longdesc is available to any user agent that wants to make it available to its users. I filed a bug for "Native user agent support for exposing longdesc to all users" last spring [1]. As stated in the change proposal [2], access to the content of the longdesc attribute for the sighted should be similar to television closed captions. Closed captions are encoded or invisible to the sighted by default and must be decoded or made visible. There is a reason that closed captions (as opposed to open captions) are the default on televisions. Sighted people rarely require them. To them, they are visual noise. Clutter. Redundant. But if a sighted person wants to enable closed captions (longdesc is not hidden meta-data [3]) they can do so via a user preference built into the system menu. It is a user choice. Televisions do not have a default on-screen visual indicator. There is no forced visual encumbrance. This is by design.
