[lltx] fontspec and calt in luatex

Hi there,

I'm using fontspec (from TL2011 as updated today).

If I don't get it wrong from the documentation, fontspec supports the
OpenType feature calt in LuaLaTeX. For some strange reason, the
following sample doesn't work:

\setmainfont[RawFeature={+calt,+ss11}]{Theano Didot}
ββ θθ

Theano Didot contextual alternates enable different glyphs for initial
and medial/final beta  (stylistic set 11 enables different glyphs for
initial and medial/final theta). Theano Didot is available at

I'm afraid that fontconfig is broken, so I cannot check with XeLaTeX
(not having XeLaTeX is fine for me).

Am I doing something wrong, is it a bug  or an unimplemented feature?

Many thanks for your help,
