[NTG-context] Subsection number independant of section

Hi, I would get a dial like this : A. Section one 1. Subsection one With the code below, I get : A. Section one A. A. Subsection one \setupsection [section] [conversion=Character] \setuplabeltext [section={{},{.}}, subsection={{},{.}}] \setupsection [subsection] [previousnumber=no] \setupbodyfont[pagella,11pt] \starttext \section{Définitions} \subsection{Approche de la loi binomiale} \stoptext Why ?
