Hi Mario,
The problem with extra vertical space with dbfo-need is with FOP. This
previous message provides more information:

Hello,
I am new on this list, so please forgive me, if this is a FAQ.
I want to use conditional page breaks, but they seem to change para spacing.
A sample docbook source looks like this:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE book>
<book version="5.0" xml:lang="de" xmlns="http://docbook.org/ns/docbook";>
<chapter>
<title>Chapter</title>
<para>Para1</para>
<para>Para2</para>
<para>Para3</para>
<para>Para4</para>
<?dbfo-need height="10cm"?>
<para>Para5</para>
<?dbfo-need height="10cm"?>
<para>Para6</para>
<para>Para7</para>
</chapter>
</book>
When I transform this document source with docbook-xsl-ns-1.78.1/fo/docbook.xsl and FOP
Version 1.1 to pdf, the para spacing between Para4/Para5 and between Para5/Para6 is
increased. I need to add space-before="0mm" to dbfo-need to make the soft page
breaks invisible, when the do not cause a page break.
Is this intentional or is there a mistake in my document, that I do not see.
I looked into pi.xsl and there seems to be a lot of code to determine correct
spacing, if space-before is missing, but I am not that fluent in xslt and
docbook, to completely understand that part.
73, Mario
