> The code runs fine with Saxon HE 12.
> Here is the sample XSLT:

>
> {code:java}
> <?xml version="1.0" encoding="utf-8"?>
> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
> version="3.0"
> xmlns:xs="http://www.w3.org/2001/XMLSchema";
> xmlns:array="http://www.w3.org/2005/xpath-functions/array";
> exclude-result-prefixes="xs array">
> <xsl:output method="xml" indent="yes"/>
>
> <xsl:template match="data">
> <xsl:variable name="array" as="item()">
> <xsl:evaluate xpath="." context-item="."/>
> </xsl:variable>
> <xsl:value-of select="array:sort($array)"/>
> </xsl:template>
> <xsl:template match="@* | node()">
> <xsl:copy>
> <xsl:apply-templates select="@* | node()"/>
> </xsl:copy>
> </xsl:template>
> <xsl:template match="/">
> <xsl:copy>
> <xsl:apply-templates/>
> <xsl:comment>Run with <xsl:value-of

> select="current-dateTime()"/></xsl:comment>
> </xsl:copy>
> </xsl:template>
> </xsl:stylesheet>
> {code}

>
> Here is the sample XML input:
> {code:java}
> <root>
> <data>[3, 2, 1]</data>
> </root>{code}
>
> Full output:
> {noformat}
