Accessibility is not a bolt-on feature, or a configurable module. It is core to the design of the whole EBDS. Some of the key accessibility features in the EBDS are:
Accessible Layout
A dedicated Layout optimised for navigation using text-browsers or screen-readers. Navigation controls are moved below content and wrapped in HTML <FIELDSET> tags. Text fills the browser width; fonts are scalable; CSS themes provide standard and high-contrast views. Try it out using the Viewing Options link at the top of the page.
Text-Only Aware Placeholder Controls
EBDS's Placeholder Controls automatically replace images with a text representation of their ALT text in Text-Only mode.
Enforced Accessibility Rules for Authors
Cubik's Web Author Console and Placeholders include enforcement of key accessibility requirements, such as Alternative Text for images.

Access Key Support
Channel Item Hyperlink controls check the item's custom properties for an Access Key definition and apply it consistently throughout the site.
Table-less Layouts
All EBDS-shipped Layouts are DIV-based to avoid confusion to non-visual browsers
Hyperlink Lists
Lists of links are always rendered as <UL><LI> lists, for maximum meaning to non-visual browsers.
