It does do a bit more as far as I understood it, e.g. it also introduce a "schredding" construct, XMLTABLE Here is an example (http://www.ibm.com/developerworks/data/library/techarticle/dm-0708nicola/) SELECT X.* FROM emp, XMLTABLE ('$d/dept/employee' passing doc as "d" COLUMNS empID INTEGER PATH '@id', firstname VARCHAR(20) PATH 'name/first', lastname VARCHAR(25) PATH 'name/last') AS X In this case the source is still a table with some XML in some column but I guess making the step to some XML collection in some XML database is not that big.
