something numbers=oldstyle could be supported but i see no real reason
for it since then we end up in endless lists of possibilities
(given all
kind of combinations)
I have not yet played with Lua, thus I can't follow your and Mojca's
discussion at that point.
But to have a handy way to switch on/off oldstyle figures would be
very useful!
"numbers=oldstyle" shouldn't be considered as a theoretical
possibility, it is needed quite often.

The following should work, can't test it at the moment
\definefontfeature[enableoldstyle][onum=yes]
\definefontfeature[disableoldstyle][onum=no]
\starttext
123 \setfontfeature{enableoldstyle} 456 \setfontfeature{disableoldstyle} 789
\stoptext
btw, these are attributes and therefore can be used grouped
123 {\setfontfeature{enableoldstyle} 456} 789
Is it also possible to inherit the values from the previuos change,
e.g. I have enabled smallcaps and I want to enable oldstyle numerals
with another command, I tried this but the old setting is forgotten and
only the new setting work, how can I do this.

\usetypescript[palatino]
\setupbodyfont[palatino]

\definefontfeature[caps][smcp=yes,lnum=yes]
\definefontfeature[onum][onum=yes]

\def\sc{\setfontfeature{caps}}
\def\os{\setfontfeature{onum}}

\starttext

Text 123 \sc Text 123 \os Text 123

\stoptext

PS: Will the smallcaps key also work in a feature release of the latin
modern fonts, thid didn't work at the moment and I was forced to use
the Pagella fonts.
