* PROBLEM DESCRIPTION: *
* In certain xmlquery where we have some nested navigation, we *
* seem to be freeing up some memory which contains important *

* XMLTABLE('$d/xml/account/billsummary/section[type=200532]/sect
* passing I.easydoc as "d" COLUMNS account_id *
* varchar(100) path '../../../../../accountNumber/text()', *
* usg_date varchar(100) path 'chargeDate/text()' ) *
* as AD *
* *
* ACCOUNT_ID *
* USG_DATE *
