"unknown namespace URI" during schema registration

Question

I have an XML containing other XMLs, grouping them together. The contained XMLs namespaces are different.
Anybody knows a way to register such an xml? (Except including the schemas into each other. I don't have the oppurtunity to change the xmls.)
Here is the example:
First the xml instance:
<?xml version="1.0" encoding="UTF-8"?>
<variables xmlns="http://www.wildom.com/neaddfel/2612">
<folder_form_2613>
<variables xmlns="http://www.wildom.com/neaddfel/2613">
<form.id>4520</form.id>
<form.type>folderform</form.type>
<form.type_id>2613</form.type_id>
<form.type_name>teszteset</form.type_name>
<form.xslt>null</form.xslt>
<t_comment/>
<t_input>2222222222222222222222</t_input>
</variables>
</folder_form_2613>
<folder_form_2614>
<variables xmlns="http://www.wildom.com/neaddfel/2614">
<form.id>4520</form.id>
<form.type>folderform</form.type>
<form.type_id>2613</form.type_id>
<form.type_name>teszteset</form.type_name>
<form.xslt>null</form.xslt>
<t_comment/>
<t_input>2222222222222222222222</t_input>
</variables>
</folder_form_2614>
<folder.company_address_city>Bp.</folder.company_address_city>
<folder.company_address_id>TuzeŠr utca 42.</folder.company_address_id>
<folder.company_address_zip>1122</folder.company_address_zip>
<folder.company_id>522</folder.company_id>
<folder.company_name>Breona kft.</folder.company_name>
<folder.hir_id>null</folder.hir_id>
<folder.id>4521</folder.id>
<folder.type_id>2612</folder.type_id>
<folder.type_name>FSDTGSH</folder.type_name>
<folder.userid>602</folder.userid>
<folder.username>[email protected]</folder.username>
<folder.xslt>FSDTGSH</folder.xslt>
</variables>
Now the xsds:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://www.wildom.com/neaddfel/2613" xmlns:xs="http://www.w3.org/2001/XMLSchema">

</xs:complexType>
</xs:schema>
As you can see, the last xsd only refers to the "variables" element in the first two.
When I register this xsd with:
DBMS_XMLSCHEMA.RegisterSchema(schemaurl=>'http://www.wildom.com/neaddfel/2612',schemadoc=>acctschema,local=>false,gentypes=>true,genbean=>FALSE,gentables=>true,force=>false,owner=>'neaddfel_xml');
I've got the error:
ORA-31154: invalid XML document
ORA-19202: Error occurred in XML processing
LSX-00023: unknown namespace URI "http://www.wildom.com/neaddfel/2614"
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 3
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 14
ORA-06512: at line 35
Is there any way to tell to XDB to use the first two xsd? I would like to store the contained xmls in the tables generated by the registration of the first two xsds.
I think I need a registerschema syntax that accepts multiple source xsd schemaurls...
Like in some validation APIs where one can define multiple xsds to validate the xml against...
Any idea?

Normally when you get an error like " "unknown namespace URI" during schema registration " you encountered one of the following issues:
- The namespace is not registered in the XMLDB repository
- The namespace is registered, but can not be found on the referred location
- The namespace is registered, but you don't have the needed privileges to call it
- You refer to an URI outside the database, which is not allowed (URI's must be registered in the repository)
