That author B uses a text editor and not an HTML-aware authoring tool is a key part of the scenario. I think it's a realistic key part. The way to mitigate this is to make only validators and authoring tools sensitive to the "missing" marker and not to make browsers/AT sensitive to it at all. -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
