DOCBOOK-APPS: SGML DocBook, Section and HTML CSS

[Carsten Wartmann <c dot wartmann at gmx dot net>]

Hello,

I am quite happy right now with SGML-Docbook right now but I
discovered a problem I could not solve alone:

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook V4.1//EN"]>

<book>

[...]

    <section>
	    <section>

	    </section>
    </section>

I am using the Recursive Sections, because it is very convinient. Now
I try to use HTML-CSS for the HTML output, this works extremely good
beside that every section level is tagged with <div class="SECTION"></div>. 
So I canīt distinguish between the levels of sections.

Do I need to go back to Explicitly numbered sections, Sect1, Sect2
etc? (this tags the sections correct in the HTML).

Or is there another way?

Thanks,
Carsten.
