> Components: Xalan, Xalan-CmdLine

> This is a bug report on the Xalan Java XSLT 3 development branch.
> While exploring the XPath 3.1 features to represent JSON arrays and objects
> as XDM 3.1 arrays and maps I have found that the XPath 3.1 instance of
> operator in Xalan currently reports true for testing the result of parse-json
> of a JSON array as the sequence type array(*) but returns false for testing
> the result of parse-json of a JSON object as the sequence type map(*).
>
> Sample XSLT code:
>
> {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:map="http://www.w3.org/2005/xpath-functions/map";
> xmlns:array="http://www.w3.org/2005/xpath-functions/array";
> exclude-result-prefixes="xs map array">
> <xsl:output method="xml" indent="yes"/>
> <xsl:template match="array">
> <array-test>
> <xsl:variable name="xdm-array" select="parse-json(.)"/>
> <array-instance-of-test>
> <xsl:value-of select="$xdm-array instance of array(*)"/>
> </array-instance-of-test>
> </array-test>
> </xsl:template>
> <xsl:template match="map">
> <map-test>
> <xsl:variable name="xdm-map" select="parse-json(.)"/>
> <map-instance-of-test>
> <xsl:value-of select="$xdm-map instance of map(*)"/>
> </map-instance-of-test>
> </map-test>
> </xsl:template>
> <xsl:template match="/">
> <xsl:copy>
> <xsl:apply-templates/>
> <xsl:comment>Run with <xsl:value-of
> select="system-property('xsl:vendor')"/> at <xsl:value-of
> select="current-dateTime()"/></xsl:comment>
> </xsl:copy>
> </xsl:template>
> </xsl:stylesheet>
> {code}

> Sample XML code:
> {code:java}
> <root>
> <map>{ "name" : "foo", "data" : [3,2,1] }</map>
> <array>[ { "name" : "foo", "value" : 3.2 } ]</array>
> </root>{code}
>
> Current output with Xalan:
> {code:java}
> <map-test>
> <map-instance-of-test>false</map-instance-of-test>
> </map-test>
> <array-test>
> <array-instance-of-test>true</array-instance-of-test>
> </array-test>{code}
>
> Expected output:
> {code:java}
> <map-test>
> <map-instance-of-test>true</map-instance-of-test>
> </map-test>
> <array-test>
> <array-instance-of-test>true</array-instance-of-test>
