Out-of-Line Storage: an Intermediate Table is not created

Question

Hi
I'm trying to use the "Out-of-Line Storage: Using an Intermediate Table to Store the List of References" sample from "Oracle XML DB Developer’s Guide".
Here are my schemas:
oebs_content_organization.xsd
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:oebs="http://www.rosbank.ru/oebs"
targetNamespace="http://www.rosbank.ru/oebs/content/organization"
xmlns:appsxx_organization="http://www.ibm.com/xmlns/prod/websphere/j2ca/jdbc/appsxx_organization_v"
elementFormDefault="qualified" xmlns:xdb="http://xmlns.oracle.com/xdb"
xdb:storeVarrayAsTable="true">
<xsd:import schemaLocation="oebs.xsd" namespace="http://www.rosbank.ru/oebs"/>
<xsd:import namespace="http://www.ibm.com/xmlns/prod/websphere/j2ca/jdbc/appsxx_organization_v"
schemaLocation="AppsXx_Organization_V.xsd"/>
<xsd:complexType name="contentOrganizationType" xdb:SQLType="CONTENT_ORGANIZATION_T">
<xsd:complexContent>
<xsd:extension base="oebs:contentAbstractType">
<xsd:sequence minOccurs="1" maxOccurs="1">
<xsd:element name="organization" minOccurs="1" maxOccurs="unbounded" xdb:SQLInline="false"
xdb:defaultTable="ORGANIZATION"
type="appsxx_organization:AppsXx_Organization_V"/>
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
</xsd:schema>
oebs_content_organization_element.xsd
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:organization="http://www.rosbank.ru/oebs/content/organization"
targetNamespace="http://www.rosbank.ru/oebs/content/organization"
xmlns:oebs="http://www.rosbank.ru/oebs" elementFormDefault="qualified"
xmlns:xdb="http://xmlns.oracle.com/xdb" xdb:storeVarrayAsTable="true">
<xsd:include schemaLocation="oebs_content_organization.xsd"/>
<xsd:import schemaLocation="oebs.xsd" namespace="http://www.rosbank.ru/oebs"/>
<xsd:element name="content" type="organization:contentOrganizationType"
substitutionGroup="oebs:contentAbstract" xdb:SQLName="CONTENT_ORGANIZATION"
xdb:defaultTable=""/>
</xsd:schema>
I registered them.
But I can't find an Intermediate Table which have to keep the List of References to the "organization" element because next select doesn't return any result:
SELECT * FROM USER_NESTED_TABLES
Can anybody give me suggestion where these references are stored and how to index them?
Thanks
Dmitry

You appear to hitting bug 5979468 which is fixed in 11g..
With the heavy usage of inheritance in your XML Schemas I would VERY STRONGLY recommend that you upgrade to 11g immediately...
