SQL & PL/SQL

Hello,
I have some problems with dbms_xmlschema.registerschema


My database is: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

My XSD schema is (SEPA pain.002.001.03.xsd) also available on this url: http://code.google.com/p/leontestbed/source/browse/trunk/bc2/sample/Schema/pain.002.001.03.xsd?r=241

After

begin
   DOK_XML_UTIL.p_vnesi_xsd_blob(401941242); -- store a XSD on file system from blob field 
   
   dbms_xmlschema.registerschema(
    schemaurl => 'http://localhost/TEST1.XSD',
    schemadoc => bfilename('ETAX_LOAD','TEST1.XSD'),
    csid => nls_charset_id('AL32UTF8'));
commit;
end;

I get:

ORA-31084: error while creating table "INIS_PROD"."Document2781_TAB" for element "Document"
ORA-02320: failure in creating storage table for nested table column "XMLDATA"."CstmrPmtStsRpt"."OrgnlPmtInfAndSts"
ORA-01792: maximum number of columns in a table or view is 1000

ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 65
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 136
