Accessibility of web content requires semantic information about widgets, structures, and behaviors, in order to allow assistive technologies to convey appropriate information to persons with disabilities. This specification provides an ontology of roles, states, and properties that define accessible user interface elements and can be used to improve the accessibility and interoperability of web content and applications. These semantics are designed to allow an author to properly convey user interface behaviors and structural information to assistive technologies in document-level markup. WAI-ARIA 1.1 adds features new since WAI-ARIA 1.0 to complete the HTML + ARIA accessibility model. It is expected this will complement HTML 5.1.
This document is part of the WAI-ARIA suite described in the WAI-ARIA Overview.

This is a First Public Working Draft of WAI-ARIA 1.1 by the Protocols & Formats Working Group of the Web Accessibility Initiative. The primary feature that is new since WAI-ARIA 1.0 is the aria-describedat
property, which aims to meet extended description use cases that are not met by aria-describedby
. The specific engineering of this feature may change and is being published now to collect public feedback both on this proposal and suggestions for other proposals. Future drafts of ARIA 1.1 will also provide a small number of features to complete the HTML + ARIA accessibility model. It is expected this will complement HTML 5.1. ARIA 1.1 will have a very limited scope. Requirements will be published in the near future. This version of ARIA 1.1 also includes a small set of editorial changes that accumulated in ARIA 1.0 after the publication of the Candidate Recommendation. A history of changes to WAI-ARIA is available.
For this publication, the Protocols and Formats Working Group primarily seeks feedback on the aria-describedat
feature, but feedback on any aspect of the specification is accepted. To comment, send email to public-pfwg-comments@w3.org (comment archive). Comments are requested by 1 November 2013. In-progress updates to the document may be viewed in the publicly visible editors' draft.
