The class extends <code>Opt_Xml_Cdata</code>, so we can use the same manipulation methods, as in case of ordinary character data nodes.</p>

<p>Note that every XML node may become a comment by setting the node flag <code>commented</code> to true. Their contents, including the node itself, will be enclosed within <code>&lt;!--</code> and <code>--&gt;</code> tags:</p>
