docbook: Fix the DocBook section output

The DocBook formatter used to generate something like:

  <para id="section"><sect2><title>Title</title></sect2>Some Text</para>

Which was completely wrong. In DocBook, a section should look like this:

  <sect2 id="section"><title>Title</title><para>Some Text</para></sect2>
