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
i assume ...
Text 123 {\sc Text 123 \os Text} 123
... is meant
no, why should I write this, this make absolutely no sense because
why should I enable odlstyle numerals and close the group before I
get them. Grouping make sense in real documents but this was only
a example and I don't nedd it here.

What I want is, write the first "Text 123" write the normal font settings,
enable for second "Text 123" small caps but use linings figures or whatever
else is the default value, this make sense in tables where I want to use
smallcaps e.g. in a title row but the numbers should remain in the local
style e.g. table numerals. My third "Text 123" pair should now be written
in smallcaps because I set it with \sc and use now oldstyle numerals.

accumulated features is something on the agenda, but we need a proper
definition interface for that; sometimes one wants to accumulate,
sometines not; sometime one even wants to kill features
I can wait for this but it should be integrated in a not so distand future.

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.
maybe there will be a lmroman10 once that has the features merged
Hans
No longer oldstyle numerals from the math fonts for latin modern,
this sound very good.
