docs: Starts a whitespace preserving section. All characters printed
  within a preserving section are printed without indentation and
  without consolidating multiple spaces. This is equivalent to
  the <tt>xml:space=&quot;preserve&quot;</tt> attribute. Only XML
  and HTML serializers need to support this method.
  <p>
  The contents of the whitespace preserving section will be delivered
  through the regular <tt>characters</tt> event.
