The "Jones" variant was introduced by this paper:


Meanwhile, the xz variant is from Appendix B of a 1992 publication the
European Computer Manufacturers Association put out about 48 track
magnetic tape cartriges, which seems to have been completely ignored
until xz picked it up.


Looking for more analysis on why xz chose an appendix of a 25 year old
standard for magnetic tape storage, I found this:


Which doesn't _directly_ address the issue but really doesn't give me
confidence in xz's design decisions.

(What _everybody_ seems to agree on is the ISO version is actively stupid.)
