How to run dynamic SQL from an ODI procedure step

Question

I am on ODI 11.1.1.6.4. From within an ODI IKM step I have no problem running a procedure step like the following which calls a pl/sql procedure to get SQL text then later runs that code. Is there anyway to do the same from within an ODI procedure? I've tried a couple of variations and can not seem to get the parsing levels to resolve within a procedure like they resolve from within a KM step.
<@
/* Setup Java variables */
String out_SQL = "";
try
java.sql.Connection sourceConnection = odiRef.getJDBCConnection("SRC");
String sqltxt = "{call set_sql(?)}";
java.sql.CallableStatement pstmt = sourceConnection.prepareCall(sqltxt);
     try
     pstmt.registerOutParameter( 1, java.sql.Types.VARCHAR);
     pstmt.execute();
out_SQL = pstmt.getString(1);
     catch(java.sql.SQLException ex)
          errMessage = ex.getMessage();
          errMessage = errMessage.replace("'","");
     finally
          pstmt.close();
catch(java.lang.Exception e)
     errMessage = e.getMessage();
     errMessage = errMessage.replace("'","");
@>
BEGIN
-- The SQL that I want to run
<@
out.println(out_SQL);
@>
-- Error handling
<@ if ( out_SQL.length() ==0 ) { @>
     raise_application_error(-20101, '<@=errMessage@>');
<@ } else { @>
     dbms_output.put_line('Successful.');
<@ } @>     
END;

Please understand that I know that I can do this all within PL/SQL -- I am explicitly doing it the way I have outlined because I want to better understand the parsing levels/behavior within ODI procedures and I want to understand why KMs steps behave differently.
Another observation -- putting this all within a pl/sql block prevents ODI from properly capturing insert/update/delete row counts like it would if it were running a SQL statement.
So the question remains -- is there a way to run a dynamic SQL statement in an ODI procedure where the SQL statement is generated from within an Oracle procedure call and then run as SQL within an ODI procedure step? Best would be if there is an example of how this can be done.
