MathML Accessibility API Mappings 1.0 (original) (raw)
Abstract
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 theelements 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.

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 inBCP 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.
There are currently no deprecated requirements.
User agents MUST conform to General rules for exposing WAI-ARIA semantics in [CORE-AAM-1.2].
User agents MUST conform to Conflicts between native markup semantics and WAI-ARIA in [CORE-AAM-1.2].
User agents MUST conform to Exposing attributes that do not directly map to accessibility API properties in [CORE-AAM-1.2].
