title: Easier topic numbering in DITA OT?
body: <p>How do I add section numbering of topics in PDF output in the DITA OT? I mean numbering like this:</p>
  
  <pre><code>1. Heading
  
       Some content
  
  1.2. Heading
  
       Some more content
  
  1.2.1. Heading
  
       Some further content
  </code></pre>
  
  <p>EDIT: My question was a bit unclear, I realize. I meant to say topic numbering (meant section in the more generic sense than section as a DITA element). Also, I know how to do this in code, but was wondering if I had missed some easier way to do this by simple configuration in the DITA OT - like a switch on or off argument or something. It's such a common request that it should be easier than having to modify stylesheets like this all the time:</p>
