Importing with Neosemantics gives prefix "xsi" for attribute "xsi:noNamespaceSchemaLocation" error

Version: Neo4j 4.4.2 community
Plugins: Neosemantics
System: Windows

I'm trying to import a XML file in to Neo4j, but I'm getting the error:

The prefix "xsi" for attribute "xsi:noNamespaceSchemaLocation" associated with an element type "Vocabulary" is not bound. [line 1, column 205]"'

Commando's that I run in the Neo4j web portal:

CREATE CONSTRAINT n10s_unique_uri ON (r:Resource) ASSERT r.uri IS UNIQUE
CALL n10s.graphconfig.init();
call dbms.procedures()
CALL n10s.rdf.import.fetch("file:///D:\\AAT\\aat_xml_1121\\AAT.xml", "RDF/XML");

First line of the AAT.xml file that I'm trying to import is:
<?xml version="1.0" encoding="UTF-8" ?><Vocabulary xsi:noNamespaceSchemaLocation="" Title="Art &#38; Architecture Thesaurus" Date="2021-10-11">
