title: how to use a parameter inside of another parameter in YAML
body: <p>So I need to append a parameter inside of another parameter.
  like this (this actually works)</p>
  
  <pre><code>parameters:
      locationMenuTop: 21142
  cjwsiteaccess.textilenetwork_de.parameters:
      locationMenuTop: %locationMenuTop%
  </code></pre>
  
  <p>but as soon as try to go one step deeper.</p>
  
  <pre><code>parameters:
      nodeSettings: 
           locationMenuTop: 21142
  cjwsiteaccess.textilenetwork_de.parameters:
      locationMenuTop: %nodeSettings.locationMenuTop%
  </code></pre>
