OK, thanks (I think).

OK. xalan also complains about a style sheet. These style sheets seem important.

$ xalan -in book.xml
XSLT Error: Failed to process stylesheet. (line -1, column -1.)

XSLException Type is: XSLTProcessorException
Message is: Failed to process stylesheet. (Unknown URI, line -1, column -1)

OK, thanks.

Out of curiosity, how do you create a PDF from a XML (DocBook) book. I
haven't had any luck with docbook2pdf, xsltproc, xalan, fop, etc. I am
amazed at how difficult the designers/architects have made this
process. Here's what the sample book looks like (the chapters are
similar):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN"
"http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd">
<book>
  <title>DocBook Authoring Guidelines</title>

  <xi:include href="bookinfo.xml" xmlns:xi="http://www.w3.org/2001/XInclude" />

  <xi:include href="ch00.xml" xmlns:xi="http://www.w3.org/2001/XInclude" />

  <xi:include href="ch01.xml" xmlns:xi="http://www.w3.org/2001/XInclude" />

  <xi:include href="ch02.xml" xmlns:xi="http://www.w3.org/2001/XInclude" />

  <xi:include href="ch03.xml" xmlns:xi="http://www.w3.org/2001/XInclude" />
</book>
