There has been a lot of discussions around
alt attributes on HTML WG mailing list. It’s always difficult to move forward in such discussions because it seems to be easy when in fact it is rather complicated. The issue involves many parameters: the author, the reader, the authoring tool or CMS, the usage pattern on the Web site and the user agent. To really be effective, we have to understand how the
alt is being authored with tools.
Steve Axthelm has sent an email describing the behavior of a few tools. Laura Carlson followed-up. Having more authoring patterns in different environments such as web services would be useful too. The list of tools so far is
- Dreamweaver CS3
- Visual Studio 2005
- Visual Studio 2008
