It's probably to do with the XML Schema namespace declarations. The
XML Schema instance namespace should be
http://www.w3.org/2001/XMLSchema-instance (you've got '1999' rather
than '2001') so change the instance document to:

<?xml version="1.0" encoding="UTF-8"?>
<person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

And the elements in the XML Schema document need to be in the XML
Schema namespace of http://www.w3.org/2001/XMLSchema. Since the schema
doesn't have a target namespace, I'd declare this with a prefix rather
than use the default namespace, so try:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="person">
        <xs:element name="name" type="xs:string"/>
        <xs:element name="age" type="xs:decimal"/>
