Incorporate it into a customization layer

  • Use the import/include two-step:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

  <xsl:import href="/sourceforge/docbook/xsl/html/docbook.xsl"/>
  <xsl:include href="tpage.xsl"/>

</xsl:stylesheet>
  • Transform with that stylesheet.

The book is also available in HTML.
