-<!-- 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="docbook.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.  -->
