Simplify HTML output for sect1 header

[Boris <boriss@web.de>]

I'm writing my first customization layer trying to simplify the HTML  
output for a sect1 header. By default I get:

<div class="titlepage"><div><div><h2 class="title" style="clear: both"><a  
name="id4699187"></a>1.1. Foo</h2></div></div></div>

However I need something really simple like:

<h2 class="title">1.1. Foo</h2>

How do I get rid of the many div elements? Do I need to look at  
html/sections.xsl or html/titlepage.xsl? And do I need to create a  
titlepage spec file (I hope there is an easier way to do something as  
simple)?
