Do authors have to use conformant tools to create accessible Web pages?
It is possible to create accessible Web pages with non-conformant tools, by using either a text editor, WYSIWYG, or other editor, and directly applying the Web Content Accessibility Guidelines 1.0 while creating the page. This may involve more steps than if using a conformant tool, for instance going into the source code to ensure that the tool is generating valid code, or performing steps manually to check the accessibility of a page. For authors who are less familiar with the Web Content Accessibility Guidelines 1.0, authoring tools that conform to ATAG 1.0 may significantly facilitate production of accessible Web sites.
