Hi,
This turns out to be a deficiency in the handling of non-namespaced
documents by the namespace stylesheets. The same thing occurs when
processing a namespaced document with the non-namespace stylesheets.
In order for the namespace stylesheets to handle a non-namespaced document,
it first preprocesses the document to generate an internal copy of the
document with the namespace added to all elements. Then the stylesheet
processes that copy, using its templates that match elements in the
namespace. However, the process of generating the copy currently omits
processing instructions and comments from the copy. That's a bug. If you
wouldn't mind, could you please file a bug report on the SourceForge site?
Thanks.

Subject: [docbook-apps] Hard page break in DocBook 4 document with
namespace-aware DocBook XSL stylesheets
Hello,
I want to insert a hard page break in the XSL-FO document obtained from a
simple DocBook XML 4 document containing the processing instruction
<?hard-pagebreak?>
and transformed with the following customization layer:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0" xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:import
href="file:///E:/kit/Docbook/docbook-xsl-ns-1.74.0/fo/docbook.xsl"/>
<xsl:template match="processing-instruction('hard-pagebreak')">
<fo:block break-after='page'/>
</xsl:template>
</xsl:stylesheet>
With the namespace aware version of DocBook XSL my template that matches
on the 'hard-pagebreak' processing instruction is never fired so the hard
page break is not inserted. With the no namespace version of DocBook XSL
the template is fired by the xsl:apply-templates element on line 350 of
docbook/xsl/fo/sections.xsl. This difference between the namespace aware
and no namespace versions is in both DocBook XSL 1.73.2 and DocBook XSL
1.74.0. Can anyone figure out why there is this difference between the
namespace aware and no namespace versions or how I could fix/work around
it so that I can insert a hard page break with the namespace aware
version?
A sample DocBook 4 document for reproducing the problem (the
xsl:apply-templates on line 350 of sections.xsl is inside a template that
matches on sect1 elements):
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN"
"http://www.docbook.org/xml/4.4/docbookx.dtd";>
<article>
<title>Article Title</title>
<sect1>
<title>Preface</title>
<para>Testing hard page break</para>
</sect1>
<sect1>
<title>Chapter 1</title>
<para>There is some text in the first paragraph.</para>
<?hard-pagebreak?>
<sect2>
<title>Subchapter 1.1</title>
<para>I want this this subchapter on a new page.</para>
</sect2>
</sect1>
</article>
Thank you,
Sorin
