[NTG-context] \setuphead[section] who do subsection inherit and how to set something just for sections?

Hello, Sorry if you get this email twice. I tried posting while I wasn't yet member of the mailing list. I didn't find where I can get more informations about this issue: I want to change the apparance of a \section so I did: \setuphead[section][style=\bf] \starttext \section{foo} \subsection{bar} \stoptext However, subsection is also in bold. If y do textstyle instead of style, then subsection doesn't inherit the style. So I have two questions: – in which documentation is described what parameters are inherited or not? – how can I change the formating of a section without changing the subsection? Thanks a lot for your help. Regards Tristram
