Implementation status for HTML5 element/attribute accessibility mappings

last updated 01/07/14

The HTML WG's Model CR Exit Criteria (Public Permissive version 3) states

For this specification to be advanced to Proposed Recommendation, there must be at least two independent, interoperable implementations of each feature. Each feature may be implemented by a different set of products, there is no requirement that all features be implemented by a single product.

Using the Model CR Exit Criteria (Public Permissive version 3) the following is asserted:

HTML ARIA mapping tables legend

= the requirement is implemented
= the requirement is not implemented
= bug found
? = not implemented or status unknown
N/A = there is no browser implementation requirement

Software used

Firefox 29
Chrome 35
Internet Explorer 11
Windows 8.1
Safari 7
OSX 10.9
aViewer
a11y-probe

Test procedure followed:

Indentify the ARIA role,state or property mapping
Look up the platform dependent mappings for the ARIA role,state or property mapping
create a test case (index of test files)
Check that the platform dependent information is exposed in at least 2 browsers.

Example test:

fieldset element is required to map to an ARIA group role
The ARIA implementation role mapping table states the ARIA role="group" maps to ROLE_SYSTEM_GROUPING in MSAA and Iaccessible2.
create a test file
Open the file in Internet Explorer 11, Firefox 29, Chrome 35 on Windows 8.1 and check the role exposed for fieldset matches the role stated in the mapping guide by using an object inspection tool such as aViewer inspect.exe or a11y-probe.
Record results and file bugs in failure cases.
