Great question! Generally, hierarchy is good, as Messrs. Wertheimer, Johnson and Chessman acclaim. But in this case, I kind of feel that the "detail" should be at the same level as the "header," if I'm understanding you correctly. In good ol' soon-to-be-sunsetted Trad*EDI, this is true: Table 1 (the header) is considered to be at the same "level" as Table 2 (the detail). The PO1 loop in the 850 PO is (implicitly) nested at the same level as typical header information like the N1 Buyer loop.
The same is true in UBL. Typical header information, which applies across the business document, consists of stuff like BuyerParty, SellerParty, Delivery (Instructions) and DeliveryTerms. These "elements" reside at the second highest level, right under the Order document root element itself. The OrderLines, which we think of as the "detail," are repeated one after another at the same level as the header information. Of course, stuff pertaining to the line item, like Quantity and Item (Description), are nested within a single LineItem within the OrderLine. The UBL Office supplies Order example instance at http://docs.oasis-open.org/ubl/cd-UBL-1.0/ shows this explicitly. William J. Kammerer Novannet, LLC. Columbus, OH 43221-3859 .

Should you build an XML document with an implied hierarchy (i.e. detail must be a child of header) or should you build it flat (i.e. detail and header at the same level? Why would one method be better than the other? > Sincerely, > __________________________________________________ > "Its not how much you know, but rather how fast you learn, and how open you are to new ideas." - Michael Dell 'Direct From Dell' > _______________________________________________ > MATTHEW P.
