Using dbms_metadata.get_ddl to get DDL but not all source provided

Today I tried to get structure of aud$ table using dbms_metadata.get_ddl. But result shows only a few lines not entire table.


SQL> select dbms_metadata.get_ddl('TABLE', 'AUD$') from dual;  
 DBMS_METADATA.GET_DDL('TABLE','AUD$')  
 -------------------------------------------------------------  
  CREATE TABLE "SYS"."AUD$"  
   (  "SESSIONID" NUMBER NOT NULL ENABLE,  
     "ENTRYI  
 SQL>  



But to get all source I used to_char function and it provide me all source.


 SQL> select   
 to_char(dbms_metadata.get_ddl('TABLE', 'AUD$'))   
 from dual;  
  CREATE TABLE "SYS"."AUD$"
