file.html: 26: parser error: Specification mandate value for attribute itemscope
</pre>
<p><a class="reference external" href="https://dev.w3.org/html5/spec-author-view/microdata.html#attr-itemscope">https://dev.w3.org/html5/spec-author-view/microdata.html#attr-itemscope</a> says:</p>
<blockquote>
The itemscope attribute is a boolean attribute.</blockquote>
<p><a class="reference external" href="https://dev.w3.org/html5/spec-author-view/common-microsyntaxes.html#boolean-attribute">https://dev.w3.org/html5/spec-author-view/common-microsyntaxes.html#boolean-attribute</a> says:</p>
<blockquote>
If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.</blockquote>
<p>So the following both are correct:</p>
<pre class="literal-block">
<div itemscope=""></div>
<div itemscope="itemscope"></div>
</pre>
</div>
</div>
<div class="phork-meta">
