<p>The <sref>aria-expanded</sref> attribute is applied to a focusable, interactive element that toggles visibility of content in a different grouping element. If the element with <sref>aria-expanded</sref> is also a <rref>treeitem</rref> in a <rref>tree</rref> or a <rref>row</rref> in a <rref>treegrid</rref>, then it SHOULD also be the <a>accessibility parent</a> of the grouping element it expands and collapses. Otherwise, the element with <sref>aria-expanded</sref> SHOULD NOT also be the <a>accessibility parent</a> of its grouping element and instead identify that relationship using <pref>aria-controls</pref>.</p>
