Included XSD-File - defaulttable

Question

Hello,
i have a xsd-file "metaddi.xsd" in which i have informations about the "main"-xsd-file. This metadata-xsd-file is included by other xsd-files:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:include schemaLocation="http://190.5.5.111:10000/home/schema/metaddi.xsd"/>
     <xs:element name="bookstore" type="bookstoreType" xdb:defaultTable="XML_BOOKSTORE">
          <xs:annotation>
               <xs:documentation>Comment describing your root element</xs:documentation>
          </xs:annotation>
     </xs:element>
     <xs:complexType name="bookstoreType" xdb:SQLType="XML_BOOKSTORE_TYPE">
          <xs:sequence>
               <xs:element name="metadata" type="metadataType"/>
               <xs:element name="content" type="contentType"/>
          </xs:sequence>
     </xs:complexType>
     <xs:complexType name="contentType">
          <xs:sequence maxOccurs="unbounded">
               <xs:element name="book" type="bookType"/>
          </xs:sequence>
     </xs:complexType>
</xs:schema>
I have e.g. 10 Main-xsd-files. So i have 10 different tables. When i make a select on elements in the metaddi.xsd so i have to address 10 tables. Is it possible to defina a defaulttable for the metaddi.xsd - so that i only have to address 1 table in a select-statement? I hope you understand my problem?
Thank you
Heidi

Hello Marco,
a view could be a solution. Defining a defaulttable is consequently not possible, isn´t it?
But how can i create a view based on several tables?
My metadata.xsd looks like:
<metadata>
<category1>country</category1>
<category2>state</category2>
<category3>city</category3>
</metadata>
The examples in the XDB Developer´s Guide are only with one table. Can you or someone else can give me please a little example how to do this?
I want a table with 3 columns:
category1 category2 category3
And the records of the different tables should be among each other. How can i do this?
Thank you very much
Heidi
