XML binary storage format impairs schema validation?

Question

I'm using Oracle 11g R1 on Windows Server 2003. I successfully registered schemas and created tables and indexes in the new binary storage format. However, when trying to load data, I'm running into problems. Schema validation behaves as if not the full feature set of XML Schema mysteriously isn't supported anymore.
There is probably more but at least wildcard elements (xs:any) and element references (xs:element ref="STH") are simply ignored in the schema definition and data is rejected even when it conforms to the schema.
Is there any solution for this or am I out of luck? I wanted to go back to CLOB storage as used in a previous installation but I'm running into problems when registering the schema. It complains about an empty SQL name although I don't have any defined. I'm pretty weirded out by all this.
I created the schema and table in a straightforward way:
begin
  dbms_xmlschema.registeruri(
    schemaurl => 'http://www.xxxhello.com/archive_tsd.xsd',
    schemadocuri => '/public/user/archive_tsd.xsd',
    gentypes => FALSE,
    options => DBMS_XMLSCHEMA.REGISTER_BINARYXML
end;
CREATE TABLE archive OF xmltype XMLTYPE STORE AS binary xml XMLSCHEMA
"http://www.xxxhello.com/archive_tsd.xsd" ELEMENT "CompleteDocument";
create index idx_lastmodified_archive on archive t
(extractvalue(VALUE(t),'/CompleteDocument/DocContent/LastModified'));Because of xs:any or element references is ignored, I get errors like
LSX-00213: only 0 occurrences of particle "REFDELEM", minimum is 1.
Thanks for your help.

The schema is very large (>200kb). Where should I upload it or can I send it to you? I'm bit concerned about confidentiality of company data. However, the instance is not valid yet. I'm in the process of modifying the schema to match all instances, but it breaks on places that should be already okay. No, I didn't use SchemaValidate ever.
But I've made an example where at least xs:any doesn't work. Element references work, though.
Sample schema:
<?xml version = "1.0" encoding = "UTF-8"?>

</CompleteDocument>Log of what I did. First I confirmed, that I could enter the instance using clob storage:
SQL> begin
  2    dbms_xmlschema.registeruri(
  3      schemaurl => 'http://www.xxxhello.com/sbreak_tsd.xsd',
  4      schemadocuri => '/public/sbreak_tsd.xsd'
  5    );
  6  end;
  7  /
PL/SQL-Prozedur erfolgreich abgeschlossen.
SQL> CREATE TABLE sbreak OF xmltype XMLTYPE STORE AS clob XMLSCHEMA
"http://www.xxxhello.com/sbreak_tsd.xsd" ELEMENT "CompleteDocument";
Tabelle wurde erstellt.
SQL> create index idx_lastmodified_sbreak on sbreak t (extractvalue(VALUE(t),
'/CompleteDocument/LastModified'));
Index wurde erstellt.
SQL> insert into sbreak values(xmltype(bfilename('DATA', 'sbreak/sbreakinstance.xml'),
NLS_CHARSET_ID('AL32UTF8')));
1 Zeile wurde erstellt.Then I deleted table and schema again:
SQL> drop index idx_lastmodified_sbreak;
Index wurde gelöscht.
SQL> drop table sbreak;
Tabelle wurde gelöscht.
SQL> begin
  2    dbms_xmlschema.deleteschema(
  3      schemaurl => 'http://www.xxxhello.com/sbreak_tsd.xsd'
  4     ,delete_option => dbms_xmlschema.delete_cascade_force
  5    );
  6  end;
  7  /
PL/SQL-Prozedur erfolgreich abgeschlossen.After that I created schema and table with binary XML storage and tried to insert the same instance again:
SQL> begin
  2    dbms_xmlschema.registeruri(
  3      schemaurl => 'http://www.xxxhello.com/sbreak_tsd.xsd',
  4      schemadocuri => '/public/sbreak_tsd.xsd',
  5      gentypes => FALSE,
  6      options => DBMS_XMLSCHEMA.REGISTER_BINARYXML
  7    );
  8  end;

aufgetretenSorry about the non-english text, but I think it can be guessed easily what's going on. Next I'll try a modifed schema without the tsd namespace added by the schema editor I use (the original large schema has been migrated from the Tamino XML database).
