Saxon » SaxonJS

So I have managed to isolate the problem, it is caused by a main XSLT module having expand-text="yes" importing a module not having that setting but using an opening curly brace {, for instance the main module is

<?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"
    exclude-result-prefixes="#all"
    expand-text="yes">
    
    <xsl:import href="include-without-expand-text1.xsl"/>
    
    <xsl:mode on-no-match="shallow-copy"/>
    
    <xsl:template match="/" name="xsl:initial-template">
        <xsl:next-match/>
        <xsl:comment xmlns:saxon="http://saxon.sf.net/">Run with {system-property('xsl:product-name')} {system-property('xsl:product-version')} {system-property('Q{http://saxon.sf.net/}platform')}</xsl:comment>
    </xsl:template>
    
</xsl:stylesheet>

the import is

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="#all"
    version="3.0">
    
    <xsl:template match="data">
        <xsl:copy>
            <span><xsl:text>{</xsl:text></span>
            <span>
                <xsl:value-of select="."/>
            </span>
            <span><xsl:text>}</xsl:text></span>
        </xsl:copy>
    </xsl:template>
    
</xsl:stylesheet>

and the xslt3 gives the error for the <span><xsl:text>{</xsl:text></span> while Saxon Java doesn't.

Input is e.g.

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <data>a &lt; b</data>
    <data>{a &lt; b}</data>
</root>

Thanks for the repro. By the looks of it, It's related to https://saxonica.plan.io/issues/5008 - specifically, it appears to be caused by losing the stylesheet-level attributes such as expand-text when declarations in an included or imported module are merged into the parent module. In this case it might be relevant that the attribute in question, expand-text="no", is implicit as the default rather than being explicitly specified.

I can confirm that importing a module that explicitly has expand-text="no" works fine with Saxon-JS 2 and xslt3.

But it is hard to fix all includes and imports of a originally XSLT 2 based project where expand-text was not used and didn't exist.
