In the A-Prompt program, the Alt text database is used to aid the author of the HTML document. I think it has several uses: 1) it can save keystrokes entering the alt text 2) it could make alt text more consistent 3) LONG DESC files are also associated with the object and alt text so they will be used more consistently Chris -----Original Message----- From: David Clark <dmclark@cast.org> To: asgilman@access.digex.net <asgilman@access.digex.net> Cc: w3c-wai-er-ig@w3.org <w3c-wai-er-ig@w3.org> Date: December 14, 1998 9:48 AM Subject: RE: remembering ALTs that go with [SRC] URLs > >I tend to agree,(I think).
