"NOT NULL value" for procedure arguments using user_arguments

Hello.

SQL> desc ccs.bongbong
PROCEDURE ccs.bongbong

 Argument Name                  Type                    In/Out Default?
 ------------------------------ ----------------------- ------ --------
 A                              VARCHAR2                IN     DEFAULT
 B                              VARCHAR2                IN

Can anyone explain to me what query 'desc' becomes? I wish to find out how it determines the default flag for the procedure arguments. This information is not in user_arguments.

SQL> select argument_name, default_value from all_arguments   2 where object_name = 'BONGBONG';

ARGUMENT_NAME                  DEFAULT_VALUE
------------------------------ --------------------

Thanks,
