title: Wix: How to set permissions for folder and all sub folders
body: <p>I know how to set the permissions for a folder:</p>
  
  <pre><code>&lt;DirectoryRef Id="ProgramFilesFolder"&gt;
    &lt;Directory Id="PHPFolder" Name="PHP"&gt;
      &lt;Component Id="PHP_comp" DiskId="1" Guid="*"&gt;
        &lt;CreateFolder&gt;
          &lt;Permission User="Everyone" GenericAll="yes" /&gt;
        &lt;/CreateFolder&gt;
  </code></pre>
  
  <p>However I need the permissions to be applied to all subfolders as well. Is this possible with out listing all the folders?</p>
