Summary: <aside> should have default implicit ARIA semantic of
"complementary"
Product: HTML WG
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: HTML5 spec

The current default implicit ARIA semantic for <aside> is "note". See section
3.2.7.4 Implicit ARIA Semantics [1].
It is proposed that this be changed to "complementary" for the following
reasons:
A. The definition of <aside> [2] seems more closely aligned to the definition
of
the "complementary" role [3] than it does to the definition of the "note" role
[4], particularly with regard to the element's content still being meaningful
when separated from the surrounding content.
B. Firefox/Win and Safari/Mac, the only two browsers currently mapping
additional semantics for <aside> to the accessibility APIs, both map it to the
"complementary" role, Firefox/Win using an IA2 "xml-roles" object attribute and
Safari/Mac an AXSubrole of AXLandmarkComplementary.
C. The HTML to Platform Accessibility APIs Implementation Guide advises that
browsers map the <aside> element to the "complementary" role where the
accessibility API permits [5].
