<p>Each platform accessibility API includes a way to assign and retrieve <a class="termref">accessible name</a> and <a class="termref">accessible description</a> properties for each <a class="termref">accessible object</a> created in the <a class="termref">accessibility tree</a>. How these properties are implemented and what they are called vary depending on the API.</p>

<p>For instance, in MSAA, all <a class="termref">accessible objects</a> support the <code>accName</code> property, which stores the object's <a class="termref">accessible name</a>. Where the object also supports having an <a class="termref">accessible description</a>, MSAA stores this property in the object's <code>accDescription</code> property.</p>

<p>Automation elements in the UIA accessibility tree have a <code>Name</code> property. Where the object also supports having an <a class="termref">accessible description</a>, UIA stores this property in the object's <code>FullDescription</code> property.</p>

<p>The approach to <a class="termref">accessible names</a> and <a class="termref" data-lt="accessible description">accessible descriptions</a> in AX API is somewhat different to the other platform APIs. <a class="termref">Accessible names</a> are exposed using the <code>AXTitle</code> property when the name is visually rendered, while the <code>AXDescription</code> property is used when the object's name is not rendered visually. An object's <a class="termref">accessible description</a>, where provided, should always be exposed in the <code>AXHelp</code> property.</p>
