DOCBOOK-APPS: saxon 6.5 not working with textinsert.extension

Platform: Intel PIII, RedHat 7.2, JDK 1.3.1, Saxon 6.5-1mdk (from the
	Mandrake Cooker distribution), DocBook 4.1.2, DocBook-XSL 1.48

(example files attached at the end)

I am trying to include example text from a separate file, into a
docbook file.  When searching the net for how to do this, I found the
following mail article:
	<http://lists.oasis-open.org/archives/docbook/200105/msg00047.html>

Short summary is:
 1. use 
	<inlinemediaobject>
	<imageobject>
	<imagedata format="linespecific" fileref="filename"/>
	</imageobject>
	</inlinemediaobject>
    to include a file

 2. set the following extensions supported by saxon and xalan
  <xsl:param name="use.extensions" select="'1'" />
  <xsl:param name="textinsert.extension" select="'1'" />

When I do this, I get error messages both when generating HTML and FO:
	cd /home/sba/tmp/docinclude/
	make -k 
	saxonbatch -o testdoc.html testdoc.xml local-html.xsl
	No insertfile extension available.
