Guideline 8 : Implement specifications that benefit accessibility
Checkpoint 8.1 : Implement accessibility features
Implement the accessibility features of specifications (e.g., markup languages, style sheet languages, metadata languages, and graphics formats).
Normative inclusions and exclusions
This checkpoint applies to both W3C-developed and non-W3C specifications.
For the purposes of this checkpoint, an accessibility feature of a specification is either:
one identified as such in the specification, or
one that allows the author to satisfy any requirement of the "Web Content Accessibility Guidelines 1.0".
The user agent is not required to satisfy this checkpoint for all implemented specifications; see the section on conformance profiles for more information.
