Reference record in another record

Question

Hi,
I have two packages each having one record. Is it possible to reference the record of the second package in the record of the first package ? For example:
create or replace pkg1 is
type rec1 is record (
col11 integer,
col12 ref pk2.col21
end pkg1
create or replace pkg2 is
type rec2 is record (
col21 integer,
col22 varchar2(20)
end pkg2
The above code always results in PLS-00532.
I don't want a nested record but something like a foreign key from one record to another...
thank you for your help,
Vanessa

You have two options:
1).
SQL> create or replace package pkg2 is
  2      type rec2 is record (
  3          col21 integer,
  4          col22 varchar2(20)
  5      );
  6  end pkg2;
  7  /
Package created.
SQL> create or replace package pkg1 is
  2      type rec1 is record (
  3          col11 integer,
  4          col12 pkg2.rec2
  5      );
  6  end pkg1;
  7  /
Package created.
SQL>2).
SQL> create or replace type rec2 is object (
  2          col21 integer,
  3          col22 varchar2(20)
  4      );
  5  /
Type created.
SQL> show errors
