Revision 720173 of contenteditable

<p class="note">{{HTMLSidebar("Global_attributes")}}</p>
<p>The <strong>contenteditable</strong> global attribute is an enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values:</p>
<ul>
 <li><span style="font-family: Courier New;">true</span> or the <em>empty string</em>, which indicates that the element must be editable;</li>
 <li><span style="font-family: Courier New;">false</span>, which indicates that the element must not be editable.</li>
</ul>
<p>If this attribute is not set, its default value is <em>inherited</em> from its parent element.</p>
<p>This attribute is an <em>enumerated</em> one and not a <em>Boolean </em>one. This means that the explicit usage of one of the values <span style="font-family: Courier New;">true</span>, <span style="font-family: Courier New;">false</span> or the empty string is mandatory and that a shorthand like <code>&lt;label contenteditable&gt;Example Label&lt;/label&gt; </code>is not allowed. The correct usage is <code>&lt;label contenteditable="true"&gt;Example Label&lt;/label&gt;</code>.</p>
