Authoring Accessible DHTML Resources
Using the W3C Role and State properties does not guarantee an accessible web resource. They can provide additional information that can improve navigation, comprehension, and usability if used correctly.
Extending Existing Functionality
Legacy Support - HTML 4.01 Workaround
The accessibility people at IBM put together a technique for enabling accessible roles and state properties in HTML. This is needed because the capability to parsing different namespaces is only supported by the newer XHTML standards. Developers may use this to upgrade older pages, especially with informative structural roles, without the additional burden of conversion to XHTML.
