I never used where-populated before. I need to look at the spec. Thank you
very much Martin!

I think you get that with the following adaption of the grouping function





     <xsl:function name="cp:group" as="node()*">

         <xsl:param name="elements" as="element()*"/>

         <xsl:param name="level" as="xs:integer"/>

         <!-- Make a variable for the heading name. -->

         <xsl:variable name="heading" select="'h' || $level"/>

         <xsl:variable name="heading-next" select="'h' || $level + 1"/>

         <xsl:for-each-group select="$elements"

group-starting-with="*[local-name() = $heading]">

             <xsl:choose>

                 <xsl:when test="self::*[local-name() = $heading]">

                     <concept id="{generate-id()}">

                         <title>

                             <xsl:apply-templates/>

                         </title>

                         <xsl:sequence select="cp:group(current-group()

except ., $level + 1)"/>

                     </concept>

                 </xsl:when>

                 <xsl:otherwise>

                   <xsl:where-populated>

                     <conbody>

                       <xsl:apply-templates select="current-group()"/>

                     </conbody>

                   </xsl:where-populated>

                 </xsl:otherwise>

             </xsl:choose>

         </xsl:for-each-group>

     </xsl:function>
