Accessibility Check
The Accessibility Checker (also known as the 508c checker) checks and reports errors that, when resolved, result in an enhanced usability ranking for published content.
The accessibility checker is typically turned on or off, system-wide, by an administrator. Depending on a user's permissions, the checker may be turned on or off at the page level as well.
When turned on, the accessibility checker is invoked after a page edit is committed by clicking the ' Submit' button. If there are any elements that the CMS deems suspect, the user is forwarded to an ' Accessibility Checker' page that lists the errors sorted by the field on the page in which they occur. These errors must be dismissed or corrected as appropriate before the page is saved.
Currently the checker will report on <table> elements without summary attributes as well as <img> tags without ALT attributes.
