title: nested array condition in TYPO3 10.4 LTS
body: <p>I need a typoscript condition working under TyYPO3 10.4 LTS</p>
  <p>I tried</p>
  <pre><code>[page[&quot;siteLayout&quot;][&quot;headerlarge&quot;] == &quot;yes&quot;]
  </code></pre>
  <p>with several variants like '' or () or point between.</p>
  <p>However, none of them is working. Could you please point me to a working solution?</p>
