The first two sections of the configuration file tell the XSLT processor where to find the DocBook XSLT stylesheets (these are imported) and which parts of your documents should be marked with comment anchors.

The most important element is the xsl:import: with the href attribute you tell the XSLT processor the path to your DocBook XSLT style sheet. You can choose chunked output here if you want.

The other thing to be configured is the list of elements that should be annotated. To change them, change the value of the match attribute, separating the tag names with a "|" character:

<xsl:template
      match="sect1|simpara|programlisting|note|important|warning|caution|tip">
      <xsl:apply-imports /> <xsl:call-template
      name="annotate"/> </xsl:template>
