If I nest parts, I stop getting TOC for the top-level part.

Hi.  I have a "part" inside a "book", and when I generate the TOC it includes the TOC for the part.

But if I have a part inside that part (which is inside a book), then I don't get a TOC for the part that is inside the book (the top-level part).

What I want is a complete TOC that lists everything from the highest level to the lowest.

Here is what I've tried:

I tried a few parameters from http://docbook.sourceforge.net/release/xsl/current/doc/html/toc_index.html that seemed like they might be relevant:

Bump up toc.max.depth.  I am going set -> book -> part -> part -> chapter.  So I'd think a depth of 5 would be enough...   let me make it 99, to give some margin...

    <xsl:param name="toc.max.depth">99</xsl:param>

I don't think this next attempt is right, it says section not part, but thought it wouldn't hurt:

    <xsl:param name="generate.section.toc.level" select="99"></xsl:param>

And let's make sure "part" is set to show up in toc:

<xsl:param name="generate.toc">

appendix  toc,title

article/appendix  nop

article   toc,title

book      toc,title,figure,table,example,equation

chapter   toc,title

part      toc,title

preface   toc,title

qandadiv  toc

qandaset  toc

reference toc,title

sect1     toc

sect2     toc

sect3     toc

sect4     toc

sect5     toc

section   toc

set       toc,title

</xsl:param>

My document is written in DocBook XML V4.4.  I'm generating HTML output using xmlto v0.0.23

I'm not sure what else to try...  there is a <toc> element but I want a dynamically generated TOC.

Any suggestions?

Best,
