While accessibility for items generated by Doc-To-Help, such as pop-up links, pop-up text and table of contents icons, is automatically enabled when Accessibility is set to Section 508 compliance, you must make sure your own content, or any content that is not generated by Doc-To-Help, is also Section 508 compliant. We recommend you read from the wide variety of guidelines and informative materials available about how to make sure your HTML content is accessible. There are also many tools available, such as Macromedia Dreamweaver's accessibility validation feature, to check accessibility in your HTML source documents. There are various third-party tools for checking accessibility, as well.
