Abstract

Accessible role and state information may be included in hypertext markup language documents by encoding an accessibility definition into a class attribute. The accessibility definition corresponds with an object of a hypertext markup language document and comprises role information and state information if state information is applicable to the corresponding role information. A script is associated with the hypertext markup language document and is configured for parsing at least a portion of the hypertext markup language document to identify the accessibility definition. The script further maps the role information and the state information in the accessibility definition to corresponding namespaced role and state attributes.
