Notification Procedure error

Question

Hi,
Oracle 8.1.7.3 Enterprise Edition.
/* Create Message Object */
CREATE type aq.Message_typ as object (
Subject VARCHAR2(30),
Text VARCHAR2(80));
/* Create Q Table. */
EXECUTE dbms_aqadm.create_queue_table (
Queue_table => 'aq.Test16_09_tab',
Multiple_consumers => TRUE,
Queue_payload_type => 'aq.Message_typ');
/* Create queue: */
EXECUTE dbms_aqadm.create_queue (
Queue_name => 'aq.Test16_09_q',
Queue_table => 'aq.Test16_09_tab');
/* Start a queue */
EXECUTE dbms_aqadm.start_queue (
queue_name => 'aq.Test16_09_q');
/* Create notification Procedure */
CREATE OR REPLACE PROCEDURE PR_NOTIFICATION (CONTEXT RAW, REGINFO SYS.AQ$_REG_INFO, DESCR SYS.AQ$_DESCRIPTOR,
                              PAYLOAD RAW, PAYLOAD1 NUMBER)
AS
DEQUEUE_OPTIONS DBMS_AQ.DEQUEUE_OPTIONS_T;
MESSAGE_PROP DBMS_AQ.MESSAGE_PROPERTIES_T;
MESSAGE_HDL RAW(16);
BEGIN
/* code */
NULL;
END;
When I attempt to compile the callback procedure an error is thrown asking to declare SYS.AQ$_REG_INFO. It simply doesn't exist when I look at DBA_OBJECTS in the SYS schema.
Any ideas as to what's happened would be greatly appreciated.
Thanks

This is what it says on my system:
SQL> show user
USER is "SYS"
SQL> desc AQ$_REG_INFO
Name Null? Type
NAME VARCHAR2(128)
NAMESPACE NUMBER
CALLBACK VARCHAR2(4000)
CONTEXT RAW(2000)
SQL> select object_name, object_type from all_objects where object_name = 'AQ$_REG_INFO' ;
OBJECT_NAME OBJECT_TYPE
AQ$_REG_INFO TYPE
1 row selected.
I think you are missing the GRANT on this TYPE to the user under which you are compiling the callback
procedure.
