That would be great indeed:

<h2 id="sec-1"><span class="section-number-2">1</span> Headline</h2>
                            \------------/ ^      
                               basename    |
                                         level

This is possible through CSS more easy and flexible (different projects,
different designs):

.outline-2 h2 {}

Ahh - Carsten, would it easy to add a new class here?


<div id="outline-container-1" class="outline-2">
<h2 id="sec-1">1 blabla </h2>
<div class="outline-text-2" id="text-1">
                ^
Here -----------'
the 

We could the indent the text independently from the headline (or add
additional indentation to the sections body).


The appended patch does both of these. Add a class to the section
number, and a class to the container of the sections content.


Regards,
