How to skip delete on logical standby

Question

Dear guys and gurus,
On next month i will have plan to delete history data on my Primary database, but i still want to keep them in logical standby as the data warehouse. So, how can i skip delete statement from primary database apply to logical standby.
Oracle SQL apply only support for Skip DML but not for keep delete statemen (on 10g and 11g)
SQL>exec dbms_logstdby.skip(statement => 'DELETE',schema_name => 'SCOTT', object_name => 'DEPT');
BEGIN dbms_logstdby.skip(statement => 'DELETE',schema_name => 'SCOTT', object_name => 'DEPT'); END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'SKIP'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
I do search and see one post about 3 years age about this question but still not answered.So, do you have any idea for this ???
So thanks and best regards.

You might want to play with this but here is an idea.
CREATE OR REPLACE PROCEDURE schema.handle_delete (
old_stmt IN VARCHAR2,
stmt_type IN VARCHAR2,
schema IN VARCHAR2,
name IN VARCHAR2,
xidusn IN NUMBER,
xidslt IN NUMBER,
xidsqn IN NUMBER,
error IN VARCHAR2,
new_stmt OUT VARCHAR2
) AS
BEGIN
-- Default to what we already have
new_stmt := old_stmt;
-- Ignore any GRANT errors on SYS or HR schemas
IF INSTR(UPPER(old_stmt),'DELETE') > 0
THEN
IF schema IS NULL
OR (schema IS NOT NULL AND
(UPPER(schema) = '<SCHEMA>' OR UPPER(SCHEMA) = '<SCHEMA>' )
THEN
new_stmt := NULL;
-- record the fact that we just skipped
END IF;
END IF;
END handle_delete;
Register the error handler with SQL Apply:
SQL> EXECUTE DBMS_LOGSTDBY.SKIP_ERROR ( -
statement => 'DML', -
schema_name => NULL, -
object_name => NULL, -
proc_name => 'SYS.HANDLE_DELETE');
