My thought was that it is present for the same reason that the
spectrum index is present--that is, it's redundant information somehow
meant to ease use of the file.

If it's not so described already, it would be nice if the
documentation indicated which elements, attributes, etc., are
redundant, just to save readers a lot of time wondering "why is this
here?".
