tAdvancedFileOutputXML "Loop Element is missing."

[_AnonymousUser]

I have a very complex xsd schema that I'm trying to write an xml file by from a csv input. I can't find a "loop" Node (under "Node Status") in the "Linker Target" pane. It could be there, but with hundreds of fields I can't find it. Anyway, tAdvancedFileOutputXML keeps telling me "Loop Element is missing."
Does anyone know what causes this error?

Apparently, it's as simple as you have to have an element set to "loop" in the "Node Status" column.
