Thanks, this is working better. Now I have a different problem. With:

[Q]
xsltproc --stringparam root.filename
lib/docbook/5/essays/bad-elements/all-in-one.xhtml.temp.xml
--path /usr/share/sgml/docbook/xsl-ns-stylesheets/xhtml-1_1
lib/sgml/shlomif-docbook/xsl-5-stylesheets/mychunk.xsl
lib/docbook/5/xml/bad-elements.xml
[/Q]

I get:

[Q]
runtime error:
file /usr/share/sgml/docbook/xsl-ns-stylesheets/xhtml-1_1/chunk-code.xsl line
432 element call-template The called template 'get.doc.title' was not found.
runtime error:
file /usr/share/sgml/docbook/xsl-ns-stylesheets/xhtml-1_1/chunk-code.xsl line
470 element choose 
Variable 'rootid' has not been declared.
[/Q]

mychunk.xsl is:

[Q]
<?xml version="1.0" encoding="ASCII"?>
<!--This file was created automatically by html2xhtml-->
<!--from the HTML stylesheets.-->

<!-- First import the non-chunking templates that format elements
     within each chunk file. In a customization, you should
     create a separate non-chunking customization layer such
     as mydocbook.xsl that imports the original docbook.xsl and
     customizes any presentation templates. Then your chunking
     customization should import mydocbook.xsl instead of
     docbook.xsl.  -->
<xsl:import href="shlomif-db5-xhtml-mydocbook.xsl"/>

<!-- chunk-common.xsl contains all the named templates for chunking.
     In a customization file, you import chunk-common.xsl, then
     add any customized chunking templates of the same name.
     They will have import precedence over the original
     chunking templates in chunk-common.xsl. -->
<xsl:import href="chunk-common.xsl"/>

<!-- The manifest.xsl module is no longer imported because its
     templates were moved into chunk-common and chunk-code -->

<!-- chunk-code.xsl contains all the chunking templates that use
     a match attribute.  In a customization it should be referenced
     using <xsl:include> instead of <xsl:import>, and then add
     any customized chunking templates with match attributes. But be sure
     to add a priority="1" to such customized templates to resolve
     its conflict with the original, since they have the
     same import precedence.

     Using xsl:include prevents adding another layer
     of import precedence, which would cause any
     customizations that use xsl:apply-imports to wrongly
     apply the chunking version instead of the original
     non-chunking version to format an element.  -->
<xsl:include href="chunk-code.xsl"/>

Previously I had a problem that while everything was in one chunk, the page was
empty.
