qbxml QuickBooks XML BillAddress invalid according to DTD - quickbooks

Question

Version 13.0 of qbxml. Why is the validator listing XML elements that are not in my XML and are not required as something it's expecting?
In all the references I've seen it lists Memo after BillAddress for InvoiceAdd.

LinePos: 22
Src Text: <BillAddress>
Reason: Element content is invalid according to the DTD/Schema.
Expecting: ItemSalesTaxRef, Memo, CustomerMsgRef, IsToBePrinted, IsToBeEmailed, IsTaxIncluded, CustomerSalesTaxCodeRef, Other, Exchange....

Answer 1

The order of the tags in qbXML is important.
If the OSR shows, for example, that the ShipMethod, ShipDate, and PONumber tags come AFTER the BillAddress tag, then you MUST follow that order.
Refer to the OSR:

Make sure your tags are in the correct order. Currently they are not due to the ShipDate, ShipMethodRef, and PONumber tags being prior to BillAddress.
