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


B  B  <xsl:function name="cp:group" as="node()*">
B  B  B  B  <xsl:param name="elements" as="element()*"/>
B  B  B  B  <xsl:param name="level" as="xs:integer"/>
B  B  B  B  <!-- Make a variable for the heading name. -->
B  B  B  B  <xsl:variable name="heading" select="'h' || $level"/>
B  B  B  B  <xsl:variable name="heading-next" select="'h' || $level + 1"/>
B  B  B  B  <xsl:for-each-group select="$elements"
group-starting-with="*[local-name() = $heading]">
B  B  B  B  B  B  <xsl:choose>
