Possible to create Oracle Database object types inside of PL/SQL?

Possible to create Oracle Database object types inside of PL/SQL?

Is it possible to create an object type inside of a package in Oracle Database 10g? Something like:

create or replace package my_package as 
    type my_type as object (
        id number(15) 
     ); 
end;

Gives:

Error(3,9): PLS-00540: object not supported in this context.

What I'm ultimately looking to be able to do is use polymorphism but also allow the objects to access tables and use PL/SQL, which isn't allowed in types defined outside of packages.

Thanks, Jeff

From the Oracle 10g documentation:

Currently, you cannot define object types in a PL/SQL block, subprogram, or package.

So, unfortunately, no.

Update for Oracle 11g Release 2:

From Chapter 3 Using PL/SQL With Object Types of Oracle Database Object-Relational Developer's Guide:

Using object types in a PL/SQL block, subprogram, or package is a two-step process.

1. You must define object types using the SQL statement CREATE TYPE, in SQL*Plus or other similar programs.

   After an object type is defined and installed in the schema, you can use it in any PL/SQL block, subprogram, or package.

2. In PL/SQL, you then declare a variable whose data type is the user-defined type or ADT that you just defined.

You can use PL/SQL in objects that are defined outside a PL/SQL package!! Use object bodies:

CREATE TYPE person_typ AS OBJECT (
  idno           NUMBER,
  first_name     VARCHAR2(20),
  last_name      VARCHAR2(25),
  email          VARCHAR2(25),
  phone          VARCHAR2(20),
  MAP MEMBER FUNCTION get_idno RETURN NUMBER, 
  MEMBER PROCEDURE display_details ( SELF IN OUT NOCOPY person_typ ));
/

CREATE TYPE BODY person_typ AS
  MAP MEMBER FUNCTION get_idno RETURN NUMBER IS
  BEGIN
    RETURN idno;
  END;
  MEMBER PROCEDURE display_details ( SELF IN OUT NOCOPY person_typ ) IS
  BEGIN
    -- use the PUT_LINE procedure of the DBMS_OUTPUT package to display details
    DBMS_OUTPUT.PUT_LINE(TO_CHAR(idno) || ' ' || first_name || ' ' || last_name);
    DBMS_OUTPUT.PUT_LINE(email || ' '  || phone);
  END;
END;
/
