      <p>
        The MathML Accessibility API Mappings (MathML-AAM) specification defines how [=user agents=] map Mathematical Markup Language (MathML) [[MathML3]] to platform <a>accessibility APIs</a>. It
        extends the Core Accessibility API Mappings (CORE-AAM) specification [[CORE-AAM-1.2]].
      </p>
      <p>
        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 <a>assistive technology</a> receives MathML content with the <a>roles</a>, <a>states</a>, and [=ARIA/properties=] it expects.
      </p>
      <p>
        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 <a>assistive technologies</a> via platform <a>accessibility APIs</a>.
      </p>
      <p>
        The MathML-AAM is part of the <abbr title="Accessible Rich Internet Applications">WAI-ARIA</abbr> suite described in the <a href="http://www.w3.org/WAI/intro/aria.php">WAI-ARIA Overview</a>.

      <p>The classification of a section as normative or non-normative applies to the entire section and all sub-sections of that section.</p>
      <p>Normative sections provide requirements that authors and user agents, and assistive technologies MUST follow for an implementation to conform to this specification.</p>
      <p>
        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.
