      Sometimes it might be useful to define
      <tc:link label="HTML Meta Tags" link="https://www.w3.org/wiki/HTML/Elements/meta"/> in a page.
      You can set e. g. search keywords anywhere on a page like
      <demo-highlight language="markup">&lt;tc:meta name="format-detection" content="telephone=\#{metaController.formatDetection ? 'yes' : 'no'}"/></demo-highlight>
      The result is a meta tag in the HTML head.
      Tobago will render these meta tags automatically, if they aren't defined:
      <demo-highlight language="markup">&lt;meta charset='UTF-8'>
&lt;meta name='viewport' content='width=device-width, initial-scale=1.0'></demo-highlight>
    </p>

    <p>
      <tc:meta name="format-detection" content="telephone=#{metaController.formatDetection ? 'yes' : 'no'}"/>
      This example toggle the Phonenumber detection on some smartphone browsers.
      <tc:selectBooleanCheckbox value="#{metaController.formatDetection}"
                                itemLabel="format detection">
          <tc:event />
      </tc:selectBooleanCheckbox>
      By selecting the checkbox a
      <br/>
      Example phone number: +1 234 567 890.
