Finding which template, formatting part of a ToC

Hi folks

On a hunt for which template I need to tweak for a table of contents in 
an article.  A clue or two from someone more expert would help!

Context is, I've got an old copy of oXygen, and I use some 
slightly-customised XSL to convert DocBook 5 to HTML, for blog posts.

I haven't needed to change any of the XSL for some years now, so I'd 
semi-forgotten what I used to know about that when I set it up - which 
even at the time was not a huge amount - but have re-reminded myself of 
some, by re-reading bits of Bob's book and posts I made to the lists at 
the time :-)

Today's problem:

When writing articles, usually I've used <section>.  Now I've added 
<section> within <section>.

In the auto-generated HTML table of contents, the layout now isn't quite 
right - it's adding some line breaks I don't want, and losing the font 
size part way through.

So I thought I'd get into the template and see what it's doing, and see 
if I can work out how to adjust it to my liking.

Step 1, find out which template is doing that bit!

The post-transform HTML contains some <dd> tags to create an indent for 
the lower-level sections, which seems like it could be a clue as to what 
the relevant bit of XSL will look like when I find it.  So I tried 
searching on <dd>.  But it turns out <dd> appears in quite a lot of the 
XSL files, so that's not enough of a clue for me to work out which one :-)

I do know which template is _calling_ the bit I'm interested in:

<xsl:template name="make.toc">

It sets up the "outer layer" of the ToC, and it's in an 
already-slightly-customised file for ToCs which is an adaptation of, I 
think, autotoc.xsl.

By looking at this previously-customised make.toc, and sticking in some 
dummy classes to see what appeared where in the HTML, I was able to 
deduce that the part of it that's actually doing the work (in this case) 
is this:

<xsl:otherwise>
   <xsl:if test="$nodes">
     <p class="toc">
       <xsl:copy-of select="$toc.title"/>
       <xsl:apply-templates select="$nodes" mode="toc">
         <xsl:with-param name="toc-context" select="$toc-context"/>
       </xsl:apply-templates>
     </p>
   </xsl:if>
</xsl:otherwise>

If I understand correctly, apply-templates is what tells the middle bit 
of the ToC to be assembled by a different template somewhere else, or 
several different templates.

I get that the with-param tag is passing a variable through to the other 
templates.

select="$nodes" mode="toc" is unfamiliar to me, I'm not sure what that's 
doing.

Logically, I assume that somewhere along the way, as well as creating 
the layout of the list, it's also taking the <title> and the xml:id of 
each <section>, and using those to assemble a link.  That bit of 
transformation could be happening in a different template from the one I 
need to tweak, though.

Any clues about finding it?

Thanks!

Jennifer
