Why is [left=(, right=)] ignored in \setupbtx when using the aps btx rendering specification? This works: \usebtxdataset [default] [../bibliography/bibliography] \setupbtx [default:cite:num] [left=(,right=)] \setupbtx [default:list] [left=(,right=),authorconversion=invertedshort] \starttext \cite[Carp:2012a, Carp:2012b] \cite[Weishaupt:2014] \cite[Knecht:2003] \cite[Jansen:2006b] \subject{References} \placelistofpublications \stoptext So, why does this not work? \usebtxdataset [default] [../bibliography/bibliography] \usebtxdefinitions[aps] \setupbtx [aps:cite:num] [left=(,right=)] \setupbtx [aps:list] [left=(,right=),authorconversion=invertedshort] \starttext \cite[Carp:2012a, Carp:2012b] \cite[Weishaupt:2014] \cite[Knecht:2003] \cite[Jansen:2006b] \subject{References} \placelistofpublications \stoptext Thank you for your help.
