If a Web site developer wanted to evaluate their current authoring tool, where would they start?
The Web site developer could review the Checklist of Checkpoints for Authoring Tool Accessibility Guidelines 1.0 and accompanying Techniques for Authoring Tool Accessibility, and compare the authoring tool against these. This would require some familiarity with ATAG 1.0 as well as the Web Content Accessibility Guidelines. Alternatively, the Web site developer could ask the developer of the authoring tool how soon that product will support ATAG 1.0.
