Setting DBMS_METADATA.GET_DDL Output for Materialized Views

Question

Hi all.
My Oracle version is 10g.
I'm extracting the DDL of all the objects from database using the DBMS_METADATA package. I'm using SET_TRANSFORM_PARAM to configure the output because I need a simple sql code, without information about tablespaces, storage and segment attributes. Everything works fine except when I'm working with mviews object types. I can't remove the information about tablespace, storage or segment attributes for materialized views.
I would like to know if there's a related issue about it. Or there's something missing in my code?
I tried to specify the object type as another parameter on DBMS_METADATA.SET_TRANSFORM_PARAM but don't work too.
The only transform parameter that works fine with Materialized Views is the SQLTERMINATOR.
See how I have done:
declare
vDDL clob;
begin
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'STORAGE', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'TABLESPACE', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'SEGMENT_ATTRIBUTES', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'SQLTERMINATOR',TRUE);
select dbms_metadata.get_ddl ('MATERIALIZED_VIEW', 'MV_STO020', 'HIS117_CHECK') into vDDL FROM DUAL;
dbms_output.put_line (vDDL);
end;
and how the output is:
CREATE MATERIALIZED VIEW "HIS117_CHECK"."MV_STO020"
ORGANIZATION HEAP PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645

Thank you in advanced!

Right. I found this way but I consider this just a quick fix, because I think there should be a better way to do this.
create table t_clob (c_long);
declare
p clob;
begin
delete from t_clob;
execute immediate 'insert into t_clob (select to_lob(query) from dba_mviews where owner = :1 and mview_name = :2)'
USING 'HIS117', 'MV_STO020';
select 'CREATE MATERIALIZED VIEW MV_STO020' || chr(10) ||
'REFRESH ON DEMAND' || chr(10) || 'AS' || CHR(10) || mv.c_long
into p
from t_clob mv;
dbms_output.put_line(p);
end;
Thanks all.
