I verified the latex set this morning and I think you are right that we can not probably do better for the Unicode-to-LaTeX mapping. I attach the updated LaTeX-commands.diff. Since I need the LaTeX-to-Unicode mapping for my math converter, I now only take the "AMS" set as a reference (+ some commands from itex2MML). The remaining issues for the AMS set are the duplicate in http://lists.w3.org/Archives/Public/www-math/2013Dec/att-0001/AMS-commands.diff as well as the question mark for <AMS>\doublebarwedge ?</AMS> (should it be \doublebarwedge or, to match unicode-math \vardoublebarwedge?). Later, I'll try to analyze more carefully the difference between what I get from unicode.xml and itex2MML (mathclass etc) and see if there is anything relevant to say.

In my opinion, keeping these "latex-historical" entries is not really useful since the changes are already recorded in the CVS history, and actually I believe using revision control system is the proper way to record this kind of info. The only potential problem I see is that this CVS repository does not seem public... or is there at least a public web page for that? -- Frédéric Wang maths-informatique-jeux.com/blog/frederic
