I can see that happening when your complete XML has more than those 'par' element and that way the template is applied without passing in a value for the parameter.

In that case it might be better to introduce a mode to process those descendants of 'par' elements e.g.


<xsl:output indent="yes"/>

  <xsl:template match="@* | node()">
      <xsl:apply-templates select="@*, node()"/>

  <xsl:template match="node()" mode="m1">
    <xsl:param name="cn"/>
    <xsl:if test="descendant-or-self::node() intersect $cn">
        <xsl:apply-templates select="@*"/>
        <xsl:apply-templates select="node()" mode="m1">
          <xsl:with-param name="cn" select="$cn"/>

<xsl:template match="par">
<xsl:variable name="p" as="element()" select="."/>
<xsl:for-each-group select="descendant::node()" group-ending-with="linebreak">
<xsl:variable name="lb" as="element()?" select="current-group()[self::linebreak]"/>
<xsl:apply-templates select="$p/@*"/>
<xsl:apply-templates select="$p/node()[descendant-or-self::node() intersect (current-group() except $lb)]" mode="m1">
<xsl:with-param name="cn" select="current-group() except $lb"/>
