What's wrong with

<xsl:template match="section">
    <xsl:copy>
        <xsl:apply-templates select="@*" mode="#current" />
        <xsl:attribute name="id"
          select="(preceding-sibling::*[1][self::target]/@refid,generate-id(.)) 
=> head()" />
        <xsl:apply-templates mode="#current" />
    </xsl:copy>
</xsl:template>

I am assuming XSLT 3, here, but that should be a fairly safe assumption
these days.
