Re: [docbook-apps] Weird appendix title indent in PDF

["Bob Stayton" <bobs@sagehill.net>]

Hi Ryan,
This is a strange one, actually.  When I examine the FO output, both the 
section title and the appendix title (and the TOC title for that matter) all 
have fo:block elements with start-indent="0pt" and margin-left="0pt", which 
should put the titles at the left margin.  When I process the file with 
RenderX XEP, that is what I get.

So at first I thought it was a bug in FOP, but I also tried Antenna House 
XSL Formatter, and that showed the same behavior as FOP. So now it seems 
there are two ways of interpreting the same FO file.

The body indent comes from a start-indent="4pc" on the fo:flow element that 
contains the page content.  An fo:flow does not generate any areas, so 
putting that start-indent property there just ensures it is inherited by all 
descendant fo:blocks, *except* those that set their own start-indent.  Since 
both the section title and the appendix title set the same property, I don't 
understand why they format differently.

I'm going to investigate this one some more.  As a workaround, you can use 
this:

<xsl:attribute-set name="article.appendix.title.properties">
 <xsl:attribute name="margin-left">-4pc</xsl:attribute>
</xsl:attribute-set>

(or if you set the $body.start.indent parameter, set it to the negative of 
that value).
