The MathML Accessibility API Mappings (MathML-AAM) specification defines how user agents map Mathematical Markup Language (MathML) [MathML3] to platform accessibility APIs. It
extends the Core Accessibility API Mappings (CORE-AAM) specification [CORE-AAM-1.2].
This specification is intended for user agent developers responsible for MathML accessibility in their product. The goal of this specification is to maximize the accessibility of MathML
content by ensuring each assistive technology receives MathML content with the roles, states, and properties it expects.
At the present time, this specification contains mappings for the subset of MathML contained in the MathML Core specification [MathML-Core]. The reason why is that this subset contains the
elements and attributes from MathML which are exposed to assistive technologies via platform accessibility APIs.
The MathML-AAM is part of the WAI-ARIA suite described in the WAI-ARIA Overview.
Status of This Document
This section describes the status of this
document at the time of its publication. A list of current W3C
publications and the latest revision of this technical report can be found
in the W3C technical reports index at
https://www.w3.org/TR/.
Publication as an Editor's Draft does not
imply endorsement by W3C and its Members.
This is a draft document and may be updated, replaced or obsoleted by other
documents at any time. It is inappropriate to cite this document as other
than work in progress.
This document was produced by a group
operating under the
W3C Patent
Policy.
W3C maintains a
public list of any patent disclosures
made in connection with the deliverables of
the group; that page also includes
instructions for disclosing a patent. An individual who has actual
knowledge of a patent which the individual believes contains
Essential Claim(s)
must disclose the information in accordance with
section 6 of the W3C Patent Policy.
As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.
The key word MUST in this document
is to be interpreted as described in
BCP 14
[RFC2119] [RFC8174]
when, and only when, they appear in all capitals, as shown here.
The classification of a section as normative or non-normative applies to the entire section and all sub-sections of that section.
Normative sections provide requirements that authors and user agents, and assistive technologies MUST follow for an implementation to conform to this specification.
Non-normative sections provide information useful to understanding the specification. Such sections may contain examples of recommended practice, but it is not required to follow such
recommendations in order to conform to this specification.
