The irony of all this of course is that, as many of us have stressed over and over again, the 1954 definition is in need of udating and improving - based on the information which has been gathered since its acceptance.
This is not to say that it can be used as a dustbin to dump anything that you happen to need a convenient label (or venue) for.
This will NOT happen while we continue to retreat into our own particular corners and slug away.
As it stands, flawed as it is, the original definition will remain in place and continue to be documented - warts and all.
