What do you mean with "doesn't seem to"? Why aren't you sure if it
works or not? Can't you provide a small but complete example that
shows a failure?

If I extend your snippet to a full minimal document it will use as
text font the default latin modern font where the mapping is enable
by default and works even without the \defaultfontfeatures command
(assuming recent versions of the packages involved.

Btw: If you use xltxtra it is not necessary to load fontspec +
xunicode as xltxtra is doing it already.
