[lltx] XeTeX vs LuaTeX font names

[Will Robertson]

Hi,

When installed in Mac OS X, the Latin Modern fonts are selected individually in XeTeX with names like 
    "Latin Modern Roman 5 Regular"

With luaotfload, however, things are different:
    ["fullname"]="LM Roman 5 Regular"

(And this name doesn't work for XeTeX.)

This leads to incompatible font names depending if the document is for XeTeX or LuaTeX; is there any way around this inconsistency?

Thanks,
