DOCBOOK-APPS: Newbie still has 3 trouble spots - Centering images,chunking per page, FOP broke

[Jeffrey Franks <jfranks@tgn.net>]

Hi,

Can someone help me with the following three problem areas?
Here is the front part of the book.xml file...

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE book PUBLIC "-//Arbortext//DTD DocBk XML V2.0//EN"
"file:////home/jlf/xae/xae/doctypes/docbook/docbookx.dtd" [
<!ENTITY ora "O'Reilly &amp; Associates, Inc.">
<!ENTITY bkinfo SYSTEM "bkinfo.xml">
<!ENTITY preface SYSTEM "preface.xml">
<!ENTITY ch01 SYSTEM "ch01/ch01.xml">
]>

<?xml-stylesheet
href="file:////home/jlf/docbook/docbook-xsl-1.40/docbook-xsl-1.40/html/xtchunk.xsl"
type="text/xsl"?>


ITEM 1: I'm having trouble getting images to center on the HTML using
XSL-1.40,
        they end up left justified.

       Here's my markup:

	<figure id="fig1-1" float="1">
	  <title>Xmt helps separate UI from application back end</title>
	  <mediaobject>
	    <imageobject>
	      <imagedata align="center" format="eps"
	      fileref="./images/fig1-1.eps"/>
	    </imageobject>
	    <imageobject>
	      <imagedata align="center" format="jpg"
	      fileref="./images/fig1-1.jpg"/>
	    </imageobject>
	  </mediaobject>
	</figure>

        Anything wrong??

ITEM 2: How do I get chunking on a per/page basis? Currently I'm just
using the
        default xtchunk.xsl with no over-rides.

ITEM 3: FOP processing fails. Here are the versions of components:
	xae 1.0 beta 6
	xt version 19991105
	xp Version 0.5
	fop fop-bin-1_17_0.jar

	Here is a failed FOP session followed by the makefile I'm using.
