Message:

Archive parser now notices the presence of a SourceSegment piece of metadata - a sure sign that the doc.xml has been generated from a bibliographic source, and also a very good reason not to extract metadata from this file given that it will not only not make sense, but will also end up with thirty-thousand bits of metadata attached to one file
