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 
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.

More comments below.

Do you know when the Unicode group will consider this change?  (and 
whether they have approved that?)

So it seems that this request to add set="latex-historical" has been 
ignored. 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?
