        <p>
                This sample shows how to configure CKEditor to output valid
                <a class="samples" href="http://www.w3.org/TR/xhtml11/">XHTML 1.1</a> code.
                Deprecated elements (<code>&lt;font&gt;</code>, <code>&lt;u&gt;</code>) or attributes
                (<code>size</code>, <code>face</code>) will be replaced with XHTML compliant code.
        </p>
        <p>
                To add a CKEditor instance outputting valid XHTML code, load the editor using a standard
                JavaScript call and define CKEditor features to use the XHTML compliant elements and styles.
        </p>
        <p>
                A snippet of the configuration code can be seen below; check the source of this page for
                full definition:
