DB2 FOR LUW / DB2FORLUW / A50 - DB2

A query which satisfies the following conditions may fail with 
an SQL0901N error: 
 
(a) the query references an XMLTABLE 
(b) the query references a column from the XMLTABLE in a 
correlated query block 
(c) the query also references the same column outside the 
correlated query block. 
 
For example: 
 
SELECT 
FROM XMLTABLE(.... 
              COLUMNS "C2" INTEGER  PATH ..., 
             ) AS XT, 
     T1 
WHERE T1.C1 = (SELECT MAX(T2.C1) 
              FROM T2 
              WHERE T2.C1 <= XT.C2) AND 
      XT.C2 >= 5
