[NTG-context] Configure \setuppublicationlayout[article] to not insert a '.' after a title ending with a '?'

Hello list, Possibly people can give me a pointer into the proper direction? What I am after is probably something like: \setuppublicationlayout[article]{% ... \insertarttitle{\bgroup }{\egroup\optionallyinsertdot }{}% ... } I am not very knowledgeable about TeX, but would this be possible? With kind regards, Renald
