I was just in the processes of making your recommended change and
found that the "FileRef" is the necessary piece to include. It took
me a day to figure this out, which really infuriates me. On the
other hand, I am thinking of having a smoke ( and I don't smoke).
I know how to upload a file to the document library, but not in this
batch command. Do you? Otherwise, I am going to upload the
document, then find it in the list and attach the properties I need.
