Referencing fields from a UDTF

In this example of a UDTF, it shows using it by referring to the fields it returns:

CREATE FUNCTION DEPTEMPLOYEES (DEPTNO VARCHAR(3))
    RETURNS TABLE (EMPNO CHAR(6),
                   LASTNAME VARCHAR(15),
                   FIRSTNAME VARCHAR(12))
    LANGUAGE SQL
    READS SQL DATA
    NO EXTERNAL ACTION
    DETERMINISTIC
    RETURN
      SELECT EMPNO, LASTNAME, FIRSTNME FROM EMPLOYEE
        WHERE EMPLOYEE.WORKDEPT = DEPTEMPLOYEES.DEPTNO

The following is a SELECT statement that makes use of DEPTEMPLOYEES:

  SELECT EMPNO, LASTNAME, FIRSTNAME FROM TABLE(DEPTEMPLOYEES('A00')) AS D



When I try something similar with my own UDTF,

create or replace function XMLFMTLOG
       (varchar(64))
       returns table
       (
         XMLrow varchar(2048)
       )
       language rpgle
       parameter style db2sql
       no sql
       not deterministic
       disallow parallel
       external name 'QGPL/SVCSQL(XMLFMTLOG)';

it fails with

Keyword FROM not expected. Valid tokens: (.
select XMLrow
  from table(xmlfmtlog(
'PROXY_2020-06-02-09.43.38.964000_log.txt')) x

It works just fine if I use

select *
  from table(xmlfmtlog(
'PROXY_2020-06-02-09.43.38.964000_log.txt')) x

What am I doing wrong?
