Details

Because Submission Attachments are completely determined by the XML data of the Submission itself, there is no direct way to entirely remove a Submission Attachment entry from the list, only to clear its uploaded content. Thus, a DELETE to the attachment's endpoint clears the uploaded bytes while the expected file slot remains listed. This endpoint clears attachments on the current version of the Submission.
