Thanks, Bob! I followed your instructions
and can now process my documents with xsltproc, Saxon, or Xalan. I appreciate
your help.

trouble using FOP to process FO file generated by Xalan or Saxon
Hi Jeff,
The XIncludes in your XML file are not resolving. That
leaves your book improperly stuctured, leading to improperly structured FO
output. You should have seen an error message from the stylesheet about
not having a template that matches "xi:include".
You need to set up either Saxon or Xalan with a recent
version of Xerces parser and with the XInclude option turned on. See this
section in my book:

Subject: [docbook-apps]
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
