XML Schema validation is incorrect when loading an XML document

example:

grant dba,resource,connect,create session,xdbadmin to scott;
conn scott/tiger
create or replace directory XSDDIR as '<path for xsd files>';
create or replace directory XMLDIR as '<path for xml files>';
grant read on directory XSDDIR to public ;
grant read on directory XMLDIR to public ;

create or replace function getXSDDocument(filename varchar2) return clob authid current_user is
xbfile             bfile;
xclob              clob;
destination_offset INTEGER := 1;
source_offset      INTEGER := 1;
language_context   INTEGER := DBMS_LOB.default_lang_ctx;
warning_message    INTEGER;
begin
xbfile := bfilename('XSDDIR', filename);
dbms_lob.open(xbfile);
dbms_lob.createtemporary(xclob, TRUE, dbms_lob.session);
DBMS_LOB.LOADCLOBFROMFILE(xclob,
                          xbfile,
                          dbms_lob.getlength(xbfile),
                          destination_offset,
                          source_offset,
                          NLS_CHARSET_ID('UTF8'),
                          language_context,
                          warning_message);
dbms_lob.close(xbfile);
return xclob;
end;
