anchors and id's

Hi,

I wrote my document in XML and gave every chapter and section an id which looks like this:

    

    For chapter:     <chapter id="ai">

    For sections:    <sect1 id="sun_ai">

                              <sect3 id="sun_or_ei">

For me this looks like a valid id names. When processing it through xsltproc, with the chunk.xsl, the linking from the TOC to an anchor in a chapter doesn't work right. It jumps somewhere near the anchor. 

The rendered Output (in TOC) looks like this:

    

       <span class="sect3">

        <a href="ch01s01.html#sun_or_ei"> Einleitung </a>

    </span>

The target looks like this:

<div>

    <h4 class="title">

        <a name="sun_or_ei"> </a>

    Einleitung </h4>

</div>

Why is it not rendered like this: 

<div>

    <h4 class="title">

        <a name="sun_or_ei"> Einleitung </a>

    </h4>

</div>

I think this is disturbing most of the browsers.

I'm using xsltproc on Mac OS X Tiger and DocBook xsl stylesheets version 1.69.1

Thank's for your response
