I'm sorry, but there seem to still be problems with primes.
Look at the height of the primes in this document (ctx-listexample30.pdf).
%%%%
%\definefallbackfamily [lucidaopentype][mm][Xits
Math][range={2660,2661,2662,2663,2664,2665,2666,2667}]
\definefontfamily[lucidaopentype][rm][Lucida Bright OT]
\definefontfamily[lucidaopentype][ss][Lucida Sans OT]
\definefontfamily[lucidaopentype][tt][Lucida Sans Typewriter OT]
\definefontfamily[lucidaopentype][mm][Lucida Bright Math OT]
\setupbodyfont[lucidaopentype,10pt]
\starttext
Look at $f'$ and $f''$
\stoptext
%%%%
If I uncomment the \definefallbackfamily, the result is the one given
in ctx-listexample30-var.pdf, look at the prime. It is still not
correct (and the double prime is wrong as in the first example).
