But he indicated he already tried in subsequent messages, so I think he
already knows by the time of reading may reply. As there are several
ways to set font features in fontspec (\defaultfontfeatures, as an
option to any of the \set*font commands, as an option to \fontspec,
\addfontfeatures) I didn't want to mention them all as it'll just
add to the confusion, or mention only one way because it might give
false message it is the only way. May intent was to say "it is a regular
options like other options you already tried", but may be I did it the
wrong way.

And there is always a manual one can refer to.
