<p>The <sref>aria-current</sref> <a>attribute</a> is a token type. Any value not included in the list of allowed values SHOULD be treated by <a>assistive technologies</a> as if the value <code>true</code> had been provided. If the attribute is not present or its value is an empty string or <code>undefined</code>, the default value of <code>false</code> applies and the <sref>aria-current</sref> <a>state</a> MUST NOT be exposed by user agents or assistive technologies.</p>

<p>The <sref>aria-current</sref> attribute is used when an element within a set of related elements is visually styled to indicate it is the current item in the set. For example:</p>

<ul>

<li>A <code>page</code> token used to indicate alink within a set ofpagination links, where thelink is visually styled to represent thecurrently-displayed page.</li>

<li>A <code>step</code> token used to indicate alink within a step indicator for a step-based process, where thelink is visually styled to represent the current step.</li>

<li>A <code>location</code> token used to indicate theimage that is visuallyhighlighted as the current component of a flow chart.</li>

<li>A <code>date</code> token used to indicate the current date within a calendar.</li>

</ul>

<p>Authors SHOULD only mark one element in a set of elements as current with <sref>aria-current</sref>.</p>

<p>Authors SHOULD NOT use the <sref>aria-current</sref> attribute as a substitute for <sref>aria-selected</sref> in widgets where <sref>aria-selected</sref> has the same meaning. For example, in a <rref>tablist</rref>, <sref>aria-selected</sref> is used on a <rref>tab</rref> to indicate the currently-displayed <rref>tabpanel</rref>.</p>
