Font features doesn't seem to work with fallback fonts (or I didn't get
it right).
See the attached file (has some comments)

keep in mind that this is still somewhat experimental and that i might
add a bit more control over things
% This doesn't use the fallback featue, so is OK
\definefont[ArabType][Arabtype*fea]
you need to keep in mind that the *featureset specification is notr
always interpreted, so you need to specify the feature with the
(symbolic) font name:
\definefontfallback [ara] [Arabtype*fea] [arabic] [force=yes]
\definefontsynonym[Arabicserif][Serif][fallbacks=ara]
% This renders Arabic, but no OpenType features
\definefont[Arabic][Arabicserif]
we might deal withthe following later but currently it is not supported
% This doesn't render Arabic too
\definefont[ArabicFea][Arabicserif*fea]
(one aspect of fallbacks is that each 'subfont' can have its own
features so inheriting from the parent font is not a good idea)

I see.

Aha, I should somehow expected that (given all the combinations I
tried).

Right, it might not be desired at all.
Thanks,
