Undocumented parameter to DBMS_XPLAN.DISPLAY_CURSOR

The documentation
http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/d_xplan.htm#i996786

tops out at

format=>'ALL'

DBMS_XPLAN.DISPLAY_CURSOR(
   sql_id           IN  VARCHAR2  DEFAULT  NULL,
   cursor_child_no  IN  NUMBER    DEFAULT  0, 
   format           IN  VARCHAR2  DEFAULT  'TYPICAL');

What if we wanted MORE ... 

First let's see what we get with 'ALL' 

set long 32000
set linesize 32000
set pagesize 0
-- set autotrace on
alter system set result_cache_mode=manual;
--select cust_first_name,cust_last_name from customers where cust_id=103379;
-- set autotrace off
select cust_first_name,cust_last_name from customers where cust_id=103379;
select * from table(dbms_xplan.display_cursor(format=>'ALL'));
quit;

System altered.

OK all as expected. 

What if we changed 'ALL' to 'ADVANCED' ?

set long 32000
set linesize 32000
set pagesize 0
-- set autotrace on
alter system set result_cache_mode=manual;
--select cust_first_name,cust_last_name from customers where cust_id=103379;

select * from table(dbms_xplan.display_cursor(format=>'ADVANCED'));
quit;
