#'   \item{provenance}{ integer: provenance of relationship. Provenance = 0 means subsumption is always true. Provenance = 1 means subsumption is usually true (but there is a theoretical risk of false positives). Provenance = 2 means both ancestors and descendents are only approximately known. Provenance = 3 means original code had at least two distinct meanings and all are being returned}
