Following the completion of WAI-ARIA 1.1, the Working Group will begin work on WAI-ARIA 1.2, which will focus on defining features that correspond to existing HTML 5 features. This reflects convergence of an accessibility taxonomy for the web across various technologies and will support future scripting and automation of accessibility features.
