What is the correct way of selecting a font and using OpenType features? I have tried

\definetypeface[linlib][rm][Xserif][Linux Libertine][features=oldstyle] \setupbodyfont[linlib, 12pt]

but the output prints Computer Modern (and not with old-style numerals). The font seems to work without the "features=oldstyle", but I am not sure how to select the font and some OpenType features. I don't seem to be able to find any documentation.

Hello, the only documentation is type-xtx.tex source code. The Xserif hack that has originally been written by Adam Lindsey now reads as: \starttypescript[Xserif][all][name] \definefontsynonym[Dummy] [name:\typescripttwo] [features=default] \definefontsynonym[Serif] [Dummy] This means that [features=default] is hardcoded into the syntax. I didn't try it, but to make something work the way you would like it, one would need to modify the hack into something like this: \definefontsynonym[Dummy] [name:\typescripttwo] [\typescriptthree] (but this would need some thinking, I do not suggest doing this modification right away even if it works). Else you can use "classical" typescripts as those in pdftex and luatex (see type-otf.tex, type-tmf.tex etc.) - numerous examples spread around. A kind-of-dirty, but most simple trick is to just redefine default features:

From font-ini.mkii:

\definefontfeature [default] [liga=yes,kern=yes,tlig=yes,trep=yes] \definefontfeature [oldstyle] [liga=yes,kern=yes,tlig=yes,trep=yes,onum=yes] Just put the following definition on top of your document: \definefontfeature [default] [liga=yes,kern=yes,tlig=yes,trep=yes,onum=yes] Mojca
