[NTG-context] how to change footnote body number

Hi there, I'm trying to change the format of the footnote numbers in the body (not in the lower area for footnotes) and I don't know how to do this. Here you have a sample: \definefontfeature[oldnumb][onum=yes] \setupnotation[footnote][numberstyle=\tf,numbercommand=\addfs{oldnumb}] \starttext Note\footnote{Not here, but above.} \stoptext Just in case you wonder, the OT feature is actually sups=yes, but that feature only works with Sorts Mill Goudy (http://www.theleagueofmoveabletype.com/sorts-mill-goudy). How is the proper way to do this? Many thanks for your help, Pablo -- http://www.ousia.tk
