For this specification to exit the CR stage, the conditions detailed in the CR Exit Criteria (Public Permissive version 3) document will have to be met. An implementation report for drawFocusIfNeeded and addHitRegion is currently in progress. The understanding is that 4 test cases (3.16, 3.19, 3.20, 3.21) still need to be produced and tested before moving to Proposed Recommendation. However, section 12 Hit regions is a feature marked at risk and may be removed from this specification before moving to Proposed Recommendation. The complete implementation report is also available.

This document was published by the HTML Working Group as a Candidate Recommendation. This document is intended to become a W3C Recommendation. W3C publishes a Candidate Recommendation to indicate that the document is believed to be stable and to encourage implementation by the developer community. This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 23 July 2015. All feedback is welcome.

This specification is an extension to the HTML5 language. All normative content in the HTML5 specification, unless specifically overridden by this specification, is intended to be the basis for this specification.
