Still ORA-19007: Schema and element do not match Error

Question

Hi all,
I'm new to XML and dealing with lots of information but I'm stuck with this error ORA-19007: Schema and element do not match. Read some forums and tried some possibitlities but none has solved this issue. I think this is related with some malformed headers definitions but I'm not sure, so any help will be much appreciated.
Here's what I've done so far:
This is the xml file - emp.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2006 rel. 3 sp2 (http://www.altova.com)-->
<employees xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/xdb/emp.xsd">
     <employee team="Team Test">
          <id>1</id>
          <name>Nelson Branco</name>
          <comment>No Comments</comment>
     </employee>
</employees>
...and this is the XSD file: emp.xsd:
<?xml version="1.0" encoding="ISO-8859-15"?>
<!-- edited with XMLSpy v2006 rel. 3 sp2 (http://www.altova.com) by Nelson Branco (Oracle Corp) -->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" elementFormDefault="qualified" xdb:storeVarrayAsTable="true">
     <xs:element name="comment" type="xs:string"/>
     <xs:element name="id" type="xs:string"/>
     <xs:element name="name" type="xs:string"/>
     <xs:complexType name="employeeType">
          <xs:sequence>
               <xs:element ref="id"/>
               <xs:element ref="name"/>
               <xs:element ref="comment" minOccurs="0"/>
          </xs:sequence>
          <xs:attribute name="team" type="xs:string" use="optional"/>
     </xs:complexType>
     <xs:element name="employee" type="employeeType"/>
     <xs:element name="employees" xdb:defaultTable="EMPLOYEES">
          <xs:complexType>
               <xs:sequence>
                    <xs:element ref="employee" maxOccurs="unbounded"/>
               </xs:sequence>
          </xs:complexType>
     </xs:element>
</xs:schema>
1) Created folders
declare
ignore boolean;
begin
ignore := dbms_xdb.createFolder('/public/Emp');
ignore := dbms_xdb.createFolder('/public/Emp/xsd');
ignore := dbms_xdb.createFolder('/public/Emp/xml');
commit ;
end;
2) Copied emp.xsd to /public/Emp/xsd in Win Explorer (via WebDAV connection)
3) Registered the schema
begin
dbms_xmlschema.registerURI(schemaURL => 'http://xmlns.oracle.com/xdb/emp.xsd'
,schemaDocURI => '/public/Emp/xsd/emp.xsd'
,genTables => true
commit ;
end ;
4) Copied the xml file to /public/Emp/xml. At this point I was expecting that the xml file was automatically uploaded to corresponding tables based on is content but it didn't happen. I didn't got any error also. When I issue:
Select count(*) from employees
...or
select y."name", y."team" from employees x, table(x.xmldata."employee") y
...got 0 rows returned
5) So then created the table:
create table emp_tab(
id number,
emp sys.XMLType
xmltype column emp
XMLSCHEMA "http://xmlns.oracle.com/xdb/emp.xsd"
element "employee";
6) And tried to insert one record based on the emp.xml:
insert into emp_tab values (1,
xmltype('<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2006 rel. 3 sp2 (http://www.altova.com)-->
<employees xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/xdb/emp.xsd">
     <employee team="Team Test">
          <id>1</id>
          <name>Nelson Branco</name>
          <comment>No Comments</comment>
     </employee>
</employees>'));
...and that when I get ORA-19007: Schema and element do not match.
Any help on this will be appreciated. Thx.
