toc generation in fo and html

[Holger Morch <morch@osiag.de>]

Hi,

I try to generate a html and a similar pdf file. The generation of the 
toc's seems to be different in html and pdf. The html Version is what I 
want.
I use docbook-xsl-1.69.1 and saxon 6.5.4.

My html toc properties are:
<xsl:param name="generate.section.toc.level" select="1"/>
<xsl:param name="toc.section.depth" select="1"/>
<xsl:param name="section.autolabel" select="1"/>
<xsl:param name="section.autolabel.max.depth" select="2"/>
<xsl:param name="section.label.includes.component.label" select="1"/>

The generated toc's are:

book toc:
1. [title]
2. [title]
3. [title]
     3.1. [title]
     3.2. [title]
     3.3. [title]
4. [title]
     4.1. [title]
     4.2. [title]
     4.3. [title]
etc.

chapter toc (number 4. in book toc):
4.1. [title]
4.2. [title]
4.3. [title]

section toc (number 4.3. in book and chapter toc):
4.3.1. [title]
4.3.2. [title]
4.3.3. [title]
4.3.4. [title]
4.3.5. [title]
4.3.6. [title]


My pdf toc properties are:
<xsl:param name="generate.section.toc.level" select="1"/>
<xsl:param name="toc.section.depth" select="2"/>
<xsl:param name="toc.max.depth">2</xsl:param>
<xsl:param name="section.autolabel" select="1"/>
<xsl:param name="section.autolabel.max.depth" select="2"/>
<xsl:param name="section.label.includes.component.label" select="1"/>

The generated toc's are:

book toc:
1. [title]...[page]
2. [title]...[page]
3. [title]...[page]
	3.1. [title]...[page]
	3.2. [title]...[page]
	3.3. [title]...[page]
4. [title]...[page]
	4.1. [title]...[page]
	4.2. [title]...[page]
	4.3. [title]...[page]
etc.

chapter toc (number 4. in book toc):
4.1. [title]...[page]
4.2. [title]...[page]
4.3. [title]...[page]
	4.3.1. [title]...[page]
	4.3.2. [title]...[page]
	4.3.3. [title]...[page]
	4.3.4. [title]...[page]
	4.3.5. [title]...[page]
	4.3.6. [title]...[page]

section toc (number 4.3. in book and chapter toc):
4.3.1. [title]...[page]
4.3.2. [title]...[page]
4.3.3. [title]...[page]
4.3.4. [title]...[page]
4.3.5. [title]...[page]
4.3.6. [title]...[page]

As you can see in pdf the sub sections 4.3.x. are included in chapter 
level toc, in html they aren't. If I set toc.max.depth to more then two 
they are in the book toc, too.
It seems that html calculates toc.section.depth depending on the level 
of the toc. In book and chapter only the first level sections are in 
toc. In the first level section only the second is included.
PDF on the other hand always include the same number of section levels 
in all toc's (2 in this example). This can only be limited by toc.max.depth.

Is this behavior as it should be? Am I doing something wrong?
