I was wondering why KEGML sounded good and off at the same time. Obviously, the letters “m” and “l” have been taken over by “machine learning” in 2022. HT-ML gets special dispensation, but willingly putting ML into your acronym these days is a just asking for confusion.
Also, the term “Markdown” is technically the legal trademark of Gruber and Swartz who created the term to take a stab at HTML. That is why CommonMark and GoldMark don’t have Markdown in the name.
