The Accessible Content module helps content authors create and manage content in a way that ensures that the content meets accessibility standards, and lets site administrators build and customize the standards the site should adhere to. When the module is enabled, it creates two kinds of nodes, a collection of Accessibility Tests, and a group of these tests called Accessibility Guidelines.
Each node type can have its own accessibility standards. To enable the module for a content type, go to the content type edit form (from admin/content/types and click on the Edit link) and look under the Accessibility Checking field-set.
This form lets the administrator control the following options, per node-type:
CCK Fields can also be checked for accessibility. Fields inherit the Guideline from the node type they are being used under, so to enable checking a field (text fields only), check the box reading enable accessibility checking.
