Hi Hans,
It seems that referencing to items is broken in the latest beta mkiv: for example in the example below the command
\in{Item}[ref:2]
does not show item number 2.
However it works fine in mkii and previous releases.
Best regards: OK
PS: a minimal example follows
%%% begin ref-item-broken.tex
\starttext
\startitemize[n]
\startitem[ref:1]
Item 1, reference 1
\stopitem
\startitem[ref:2]
Item 2, reference 2
\stopitem
\startitem[ref:3]
Item 3, reference 3
\stopitem
\stopitemize
See \in{Item}[ref:2] above.
\stoptext
%%% end ref-item-broken.tex
