<xsl:output method="xml" indent="yes"/>
<xsl:param name="chunk-size" as="xs:integer" select="3"/>
<xsl:template match="/">
<xsl:for-each-group select="items/item" group-adjacent="(position()
- 1) idiv $chunk-size">
<chunk number="{position()}">
<xsl:sequence select="current-group()"/>
</chunk>
</xsl:for-each-group>
</xsl:template>
