The comment just above that refers to [1], which says:

  "Magic numbers that apply to ODF document category subtypes
  incorporate the magic number for ZIP_PK, the string mimetype at
  position 30, and the MIME subtype string value at position 38."

And lists application/vnd.oasis.opendocument.database as the mime
type.

I don't know whether any such files exist, but I would suggest not
removing it as long as this is how the LoC describes the format.

Perhaps the LoC page should be amended?
