Hi, there,

(I'm on the latest version of Oxygen Author, using FOP PDF transform).

I'd like to use a  Dcobook processing instruction for page breaks on PDF -- as mentioned in Bob's book. http://www.sagehill.net/docbookxsl/PageBreaking.html#HardPageBreaks

I'd like to use one of the Oxygen transforms for Docbook. What are my options here? I see that in the transform dialog you have an "Additional XSLT stylesheet" option on the XSLT tab. Can I use that?

I created a file pi-docbook.xsl which is just  this:


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"
    xmlns:d="http://docbook.org/ns/docbook"
    exclude-result-prefixes="d"
    xmlns="http://www.w3.org/1999/xhtml" version="1.0">
    <xsl:template match="processing-instruction('hard-pagebreak')">
        <fo:block break-after='page'/>
    </xsl:template>     
</xsl:stylesheet>

If I add this simple XSL file to use as an additional XSLT stylesheet (in the Edit Scenario dialog--> XSLT tab),  it gave me an error.  (See below). It seems to give me some prolog errors.  I have used processing instructions successfully if I download my own Docbook XSLT and transform my project using a customization layer (which then imports the docbook files).  I know how to do that.

But I'm working for a client and would like to give them something easy which they can do entirely with the Oxygen transforms. Do you have any ideas about how to do PIs?  or do you know why I get this error message? thanks.
