Hi Dave,One problem I see with your customization is here:<xsl:otherwise>

That param is a unitless integer, meant to be used in math expressions. It needs to have 'pt' added to it to make sense. I'm not sure why that would have the effect you are getting, but try fixing that first.----- Original Message -----From: XmplarTo: DocBook AppsSent: Saturday, July 07, 2012 12:07 AMSubject: [docbook-apps] listitem not creating vertical space for mediaobjectI cannot get screenshots (wrapped in mediaobject) to display correctly with enough vertical space in either an orderedlist or itemizedlist. I've compared the fo output for my customization and the standard stylesheets (DB 1.76.1), looking closely at all markup for lists from the fo:list-block, down to the fo:block surrounding each fo:external-graphic. Here's my debugging so far:
Using DB 1.76.1 stylesheets
In the standard stylesheets, screenshots are formatted in mediaobject (both with and without being wrapped in informalfigure) and appear correctly within listitems:
<!--[if !vml]-->
<!--[endif]-->
The relevant FO for that listitem is:
<fo:list-item space-before.optimum="1em" space-before.minimum="0.8em"
space-before.maximum="1.2em" id="d0e975">
<fo:list-item-label end-indent="label-end()">
<fo:block>3.</fo:block>
</fo:list-item-label>
<fo:list-item-body start-indent="body-start()">
<fo:block><fo:block>In the final screen, click on Install. That will launch Serna.

/></fo:block></fo:block><fo:block space-before.optimum="1em"
space-before.minimum="0.8em" space-before.maximum="1.2em">Close that window and
exit Serna.</fo:block></fo:block>
</fo:list-item-body>
</fo:list-item>Using customized stylesheets
In my customization I have screenshots that are in a mediaobject (I’ve also tried wrapping in informalfigure):
<!--[if !vml]-->
<!--[endif]-->
This is the following page where I’ve tested putting the mediaobject outside an orderedlist (in body text). This does create space for the screenshot (the section title 4.2 occurs below the screenshot):
<!--[if !vml]-->
<!--[endif]-->
I get the same result in an itemizedlist:
<!--[if !vml]-->
<!--[endif]-->
The FO for that listitem is:
<fo:list-item space-before.optimum="1mm" space-before.minimum="1mm"
space-before.maximum="1mm" id="d0e975">
<fo:list-item-label color="#000000" font-size="12" end-indent="label-end()">
<fo:block>3.</fo:block>
</fo:list-item-label>
<fo:list-item-body start-indent="body-start()">
<fo:block><fo:block space-before.optimum="0mm" space-before.minimum="0mm"
space-before.maximum="0mm" space-after.minimum="3mm" space-after.optimum="5mm"
space-after.maximum="7mm" line-stacking-strategy="font-height">In the final

</fo:list-item>
I cheated a little by adding a “space-before” value in the fo:block (highlighted in yellow above) preceding the external-graphic, and created space for the screenshot, but that seems impractical. I’ve deleted attributes for line-stacking-strategy, space-after and space-before values, with no effect.
Here’s the markup:
<para><emphasis role="bold">Exercise 1</emphasis><orderedlist numeration="arabic">
<listitem>
<para>In a web browser, go to <link
xlink:href="http://downloads.syntext.com/serna-free/4.4.0-RELEASE/"/>. This has
different versions for Windows, Macintosh or Linux operating systems.</para>
</listitem>
<listitem>
<para>Download the respective file for your computer (.exe, .dmg or linux.tgz). Save the
file to your desktop or a convenient temporary directory. Double-click on the downloaded
file and follow the instructions at each step to set up the software. You can choose to
set up the software files in the Program Files directory (<emphasis>C:/Program
Files</emphasis>) or another convenient directory that you have permission to access.
Use all the default settings in the screen <quote>Select Additional
Tasks</quote>.</para>
</listitem>
<listitem>
<para>In the final screen, click on Install. That will launch Serna. When Serna starts, a
window titled <quote>Examples</quote> may appear. At the lower left, click on the
checkbox <quote>Don<?apos?>t show this dialog on startup</quote>.</para>
<informalfigure pgwide="1">
<mediaobject>
<textobject>
<phrase>window showing example documents</phrase>
</textobject>
<imageobject role="pdf">

<imageobject role="epub">

</imageobject>
<imageobject role="web">

</informalfigure>
<para>Close that window and exit Serna.</para>
</listitem>
<listitem>
<para>In your file manager, create a directory (for example, under the
<emphasis>C:/</emphasis> drive) in which to put the XML files that you will create in
the exercises. Name this directory <emphasis>xmlfiles</emphasis>.</para>
</listitem>
</orderedlist></para>
And part of my customization for orderedlist properties:
<xsl:attribute-set name="orderedlist.properties" use-attribute-sets="list.block.properties">
<xsl:attribute name="font-family">
<xsl:choose>
<!--for lists within 'table' or 'example', use same font style as surrounding text-->

<xsl:otherwise>
<xsl:value-of select="$body.fontset"/>
</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
<xsl:attribute name="font-size">
<xsl:choose> <!-- change font size of text for numbered list

<xsl:attribute name="color">
<xsl:value-of select="$orderedlistcolour"/>
</xsl:attribute> <!-- text colour: specify web colour, e.g. #ff0000*****works 24/9/11 -->
</xsl:attribute-set>I'm sure that the "height" and "contentheight" in the markup has no bearing on the result. Thanks in advance.
