ORA-19202: Error occurred in XML processingLSX-00023: unknown namespace URI

Question

Hi there
I am trying to register an XSD document as an XML schema on the database. I am using Oracle 9i release 9.2.0.5.0 and using the dbms_xmlschema.registerSchema method in PL/SQL.
I am getting the following error when trying to register:
ORA-19202: Error occurred in XML processing LSX-00023: unknown namespace URI
The problem seems to be caused by a local simpleType declared outside of the root element. If I remove the simpleType from the xsd, I can register it successfully as a schema on the database. However, we need the simpleType there as it defines valid values for one of the elements in the xsd.
The xsd follows the structure:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.oracle.com/VFLOC.xsd"
xmlns:vfloc="http://www.oracle.com/VFLOC.xsd"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb">
     <xsd:element name="VisionDataExchange">
          <xsd:complexType>
               <xsd:sequence>
                    <xsd:element name="Credentials">
...... etc. etc.
               </xsd:element>
               </xsd:sequence>
          </xsd:complexType>
     </xsd:element>
     <!-- Data Types Must complete data type values from database -->
     <xsd:simpleType name="TrueFalseType">
          <xsd:restriction base="xsd:string">
               <xsd:enumeration value="1"/>
               <xsd:enumeration value="0"/>
               <xsd:enumeration value="True"/>
               <xsd:enumeration value="False"/>
          </xsd:restriction>
          <!-- 1 and 0 are preferred -->
     </xsd:simpleType>
</xsd:schema>
Does anyone know how I can register a schema with a targetNamespace and the local simpleType below?
Any help would be much appreciated.
Thanks!
