i'll add a (plain) example to the distribution

you can change this on the def file:

	local sometext=(R("az","AZ","09")+S("+-.{}"))^1

and then in the vf lua file

         local name, rest = string.match(v,"^(.-){(.*)}$")

and then

     \font\crapa=lmroman12-regular:mode=base;liga=yes;kern=yes; at 12pt
     \font\crapb=lmsans12-regular:mode=base;liga=yes;kern=yes;  at 30pt
at 12pt

kind of works ok (not in context but that doesn't matter)

the generic spec parser (as context itself uses a different one).
