Benefits of conformance
- Allows universal access (for all users) through support for:
- user agents and assistive technologies that cannot process scripts and objects.
- users who due to security or performance concerns disable scripts and objects in their browser (user agent).
Risks of non-conformance
- Customer complaints.
- Failure to comply with accessibility requirements of Websites policy (IS26).
The use of scripting to improve the user experience is encouraged; however users must be able to complete any process with client-side scripting disabled. Techniques of progressive enhancement support a richer experience without compromising accessibility.
This requirement also ensures universal access by all users, browsers and devices (including mobile devices).
