<h2 id="howto">How to use the RGAA</h2>
<p>
The RGAA applies to any HTML content (HTML4, XHTML1, HTML5). For some tests, a reference baseline is used. This baseline takes into account a set of assistive technologies, browsers and operating systems, on which the accessibility of JavaScript-based interface components must be tested, among others. A detailed description is provided here: <a href="./baseline.html">Baseline</a>.
</p>
<h3>Important notice regarding HTML content prior to HTML5 specification</h3>
<p>When the HTML code of the page is <em>not</em> HTML5, the HTML5 elements (tags and attributes) required by a criterion or test, are not applicable. Every other criteria or tests remain applicable, including those related to ARIA attributes, states or properties. The following criteria and tests are not applicable:
</p>
<ul>
<li>Criterion 1.10;</li>
<li>Criterion 9.2;</li>
<li>Test 11.10.1 (condition 2, relative to the HTML5 attribute <code>required</code>).</li>
</ul>
<h3>Validation process</h3>
<p>
For each criterion, compliance is defined as follows:
</p>
<ul>
<li>Conforming (C): all applicable tests are passed</li>
<li>Non Conforming (NC): at least one applicable test is failed</li>
<li>Not Applicable (NA): there is no content targeted by the criterion.</li>
</ul>
<p>
The RGAA proposes two additional compliance statuses:
</p>
<ul>
<li>Derogated (D): some contents targeted by the criterion will meet compliance by derogation</li>
<li>Not tested (NT): the criterion has not been tested.</li>
</ul>
<p>You can get further information about the RGAA validation process in the <a href="./rgaa-companion-guide.html">RGAA companion guide</a>: How is RGAA conformance verified?</p>
