How to burst BI Publisher reports that use PL/SQL Procedure call?

I've used the following PL/SQL code:

DECLARE

	TYPE REFCURSOR IS REF CURSOR;

	XDO_CURSOR REFCURSOR;

	L_DATA_CLOB CLOB;

BEGIN

	L_DATA_CLOB :=

		L_DATA_CLOB

		||'<error_message>'

		||'SUCCESS'

		||'</error_message>'

		||'<status>'

		||'OK'

		||'</status>';


	OPEN :XDO_CURSOR FOR SELECT L_DATA_CLOB FROM DUAL;

END;

The following bursting code has been used:

SELECT

	NULL KEY,

	'PLSQL_Layout' TEMPLATE,

	'en-US' LOCALE,

	'PDF' OUTPUT_FORMAT,

	'Test_'|| TO_CHAR(SYSTIMESTAMP, 'YYYYMMDD_HH24MISS')||'.pdf' OUTPUT_NAME,

	'EMAIL' DEL_CHANNEL,

	'{my_email}' as PARAMETER1,

	NULL PARAMETER2,

	'{our_usual_sender}' PARAMETER3,
