I’m using Oxygen 24 with Saxon-EE 9.9.1.7 and I’m trying to run XSLT in the debugger but it fails to run however if I just run it outside of the debugger it does run?

I’m running an XSLT over the following source XML doc:

    <MSG02>
      <IDOC BEGIN="1">
          <E1EDK01 SEGMENT="1">
              <BELNR>1</BELNR>
          </E1EDK01>
        <E1EDK03 SEGMENT="1">
          <IDDAT>001</IDDAT>
          <DATUM>20240430</DATUM>
        </E1EDK03>
        <E1EDKT1 SEGMENT="1">
          <TDID>Z001</TDID>
          <TSSPRAS>D</TSSPRAS>
          <TSSPRAS_ISO>DE</TSSPRAS_ISO>
          <E1EDKT2 SEGMENT="1">
            <TDLINE>POconfType:accept;</TDLINE>
            <TDFORMAT>=</TDFORMAT>
          </E1EDKT2>
        </E1EDKT1>
        <E1EDKT1 SEGMENT="1">
          <TDID>Z001</TDID>
          <TSSPRAS>E</TSSPRAS>
          <TSSPRAS_ISO>EN</TSSPRAS_ISO>
          <E1EDKT2 SEGMENT="1">
            <TDLINE>POconfType:accept;</TDLINE>
            <TDFORMAT>=</TDFORMAT>
          </E1EDKT2>
        </E1EDKT1>
      </IDOC>
    </MSG02>

With the following XSLT:

    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0"
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:saxon="http://saxon.sf.net/"
        exclude-result-prefixes="#all">
        <xsl:param name="xquery-param1" as="xs:string" expand-text="no"><![CDATA[
                element E1EDKT1 {attribute SEGMENT {"1"}, 
                    element TDID { "ZG04" }, 
                        if (exists(/*/IDOC/E1EDKT1[TDID="ZG04"]/E1EDKT2/TDLINE)) then 
                            (element TSSPRAS {"E"},
                             element TSSPRAS_ISO {"EN"},
                                for $kt in (/*/IDOC/E1EDKT1[TDID="ZG04"][1]/E1EDKT2/TDLINE)
                                return
                                    element E1EDKT2 {attribute SEGMENT {"1"},
                                    $kt
                                    }
                            )
                        else(),
                        if (exists(/*/IDOC/E1EDK01/BELNR)) then
                            ( element E1EDKT2 {attribute SEGMENT {"1"},
                              element TDLINE { concat("DateOfSupply:",/*/IDOC/E1EDK03[IDDAT="001"]/DATUM/concat(substring(.,1,4),"-",substring(.,5,2),"-",substring(.,7,2))) }
                              }
                            )
                        else()
                }
      ]]></xsl:param>
        <xsl:output indent="yes"/>
        <xsl:variable name="xquery1" select="saxon:compile-query($xquery-param1)"/>
        <xsl:template match="/" name="xsl:initial-template">
            <xsl:apply-templates select="*"/>
        </xsl:template>
        <xsl:template match="@*|node()">
            <xsl:copy>
                <xsl:apply-templates select="@*|node()"/>
            </xsl:copy>
        </xsl:template>
        <xsl:template match="E1EDKT1[1]">
                <xsl:copy-of select="saxon:query($xquery1)"/>
        </xsl:template>
    </xsl:stylesheet>

Before debugging I get the following warning:

• For parameter ‘xquery-param1, the variable/parameter $kt should be placed in a ‘Text Value Template’

When I run the debugger I get:

• W Evaluation will always throw a dynamic error: Namespace prefix {myfunc} has not been declared
• E Internal error evaluating template rule at line 29 in module file:/C:/…

The error stops the debugger from completing whereas if I do a normal run it generates an output as expected?
