Right now, the Takedown Tools outputs wikitext to place on the Foundation wiki for historical reference. This page makes use of the [[ | DMCA email]] template, which includes a field for an attachment if there is one. Unfortunately the parser isn't clever enough to know that a blank entry here means "null", rather than just a blank string.
Ideally the tool would work out that no attachment was uploaded, and therefore doesn't need to be in the wikitext output by the tool.
