Agreed, but there also a number of minor problems. Off hand I recall:

- non-US date formats can lead to errors.
- it cannot differentiate between satellites with the same NORAD number
  but different names. You might need this to test different elsets
  for the same satellite.
- it employs a checksum algorithm different from what appears to be
  the USSPACECOM convention. The problem is with the plus (+) sign.
