Assistive Tools

The WRI will develop or aid in the development of tools that help Web Publishing Systems produce accessible Web sites. Such a tool could be a syntax validator. Another tool could be an automated accessibility testing tool.

Such tools should, where possible, be made available in several forms:

• stand-alone
• as modules or plug-ins for
  • Web Publishing Systems
  • Web browsers
• on-line
