I've tried a small XSLT transformation example, to explore this point.
Below are my findings,

test input XML:

<?xml version="1.0" encoding="UTF-8"?>
<test>
   <hello/>
</test>

test input XSL stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                         version="1.0">

    <xsl:output method="xml" indent="yes"/>

    <xsl:template1 match="/">
          hello
    </xsl:template1>

</xsl:stylesheet>
(this stylesheet has an invalid element  xsl:template1 in XSLT namespace)

java program (mainly written, for using Oracle JDK 11's XSLT
transformation) to invoke the XSLT transformation,

import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import java.io.*;

public class XSLTTest {

   public static void main(String[] args) {

   try {
               TransformerFactory tFactory =
TransformerFactory.newInstance();

               Transformer transformer = tFactory.newTransformer(new
StreamSource(args[1]));
               transformer.transform(new StreamSource(args[0]), new
StreamResult(System.out));
           }
           catch(Exception ex) {
         ex.printStackTrace();
           }
     }
}

Oracle JDK's 11.0.2 XSLT processor produces following result,

ERROR:  'line 7: Unsupported XSL element 'template1'.'
FATAL ERROR:  'line 7: Unsupported XSL element 'template1'.'
javax.xml.transform.TransformerConfigurationException: line 7: Unsupported
XSL element 'template1'.

(this clearly shows that, Oracle Java 11 XSLT processor is based on Xalan,
and by default it uses Xalan's XSLTC mode)

Apache Xalan-J 2.7.2 (running with JDK 1.8) produces following result, with
the invoked command line,

java org.apache.xalan.xslt.Process -in foo.xml -xsl foo1.xsl
file:///E://foo1.xsl; Line #7; Column #30; xsl:template1 is not allowed in
this position in the stylesheet!

Apache Xalan-J 2.7.2 (running with JDK 1.8) produces following result, with
the invoked command line (using XSLTC option),

java org.apache.xalan.xslt.Process -XSLTC -in foo.xml -xsl foo1.xsl
(Location of error unknown)line 7: Unsupported XSL element 'template1'.
(Location of error unknown)Could not compile stylesheet

(Location of error unknown)XSLT Error
