BaseX 9.1.2 : issues with entities on xslt:transform - xslt

Question

I'm having some trouble to transform xml nodes containing entities using xslt:transform() with BaseX :
let $xsl := doc('xsl/commun.xsl')
return
xslt:transform(<node>ééé</node>, $xsl)
gives
[FODC0002] "" (Line 1): L'entité "eacute" était référencée, mais pas déclarée.
I have created my database with/without intparse and/or DTD options, with no changes (options basex).
xslt:processor() and xslt:version tell that I'm using java 1.0 as processor.
Here is the declaration of my xslt:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:tei="http://www.tei-c.org/ns/1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" encoding="UTF-8" omit-xml-declaration="no" exclude-result-prefixes="#all"/>xslt:transform
<xsl:template match="/"/>
I don't know what I am doing wrong... Should I declare any entity I want to use in the XSL file?

Answer 1

xslt:processor() and xslt:version tell that I'm using JAVA 1.0 as processor.
As explained here "XSLT 3.0 will be enabled if Version 9.x of the Saxon XSLT Processor (saxon9he.jar, saxon9pe.jar, saxon9ee.jar) is found in the classpath"
Just has to add saxon9he.jar in {Basex Folder}/lib/custom and that's fine
Hope that help
