Howto? XMLSchema validation on abstract/substitutionGroup and complexType

Question

Hi, I'm following the examples on [http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96621/adx06scj.htm|http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96621/adx06scj.htm] .
A little change and it worked for me. I wanted to try out a schema construction from the XBRL world, but it seems to fail somewhere on the abstract/substitionGroup contruction when combined with custom types.
I keep getting:
catalogue.xml<Line 11, Column 36>: XML-24534: (Error) Element 'testitem' not expected.
catalogue.xml<Line 12, Column 15>: XML-24534: (Error) Element 'Book' not expected.
catalogue.xml<Line 19, Column 15>: XML-24534: (Error) Element 'Book' not expected.
Removing the attribute from the XMLSchema and setting type=String instead of stringItemType does let xmlparserv2 validate the file.
An editor like EditiX does validate the XML file against the Schema.
xmlparserv2.jar from .xdk_version_10.2.0.2.0_production
How do I solve this?
The file, notice the testitem:
<?xml version="1.0"?>
<Catalogue xmlns="http://www.publishing.org/namespaces/Catalogue"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=

cat.xsd">

The XMLSchema, notice the type=anyType, stringItemType and element testitem:

Thanks you for the information!
Shape of the document conforms to the schema. Data types are correct. Shape means hierarchy of elements and element names, correct data types in the sense of build in SQL data types to store the information in the tables?
On the other side, xsd:restriction, xsd:unique, xsd:key/keyref,... is not checked?
OK. Now I can know what happens when no validation constraint is defined.
It is a good idea to give the developer the choise ;-)
but I feel uncomfortable when I can enter non-valid XML data. In my applications, I would like to have the validation turned on!
Please, lets go back to my first posting in this thread:
When inserting an XML document into a table with XML Schema validation I get an ORA-03113!
What does wrong?
