Taking a quick look I wonder whether it is not related to the empt url in
<fo:external-graphic src="url()"
width="2.925in" height="0.665in" content-width="2.925in"
content-height="auto"/>
When I "fix" that I see another error which seems to indicate something is
wrong with fo file.

Subject: trouble using FOP to process FO file generated by Xalan or Saxon
I was using xsltproc as my XSLT processor, but it ran out of memory on a
large book, so I decided to try Xalan and Saxon to convert a test book. I
set up Xalan and Saxon according to the instructions in Bob Stayton's book,
DocBook XSL: The Definitive Guide
(http://www.sagehill.net/docbookxsl/index.html). However, when I try to use
FOP 0.93 to convert either of the attached FO files, it reports the
following exception:
org.xml.sax.SAXParseException: Content is not allowed in prolog.
I pasted full output of the exception below.
Has anyone else experienced this problem? Please take a look at the attached
FO files and tell me what's wrong.
Regards,
Jeff Powanda
