[NTG-context] how to redefine section headers

hi! i want to achieve the effect i see when using the following code, only in a semantically correct way (and without defining a \MyHeader macro like in some examples) \setuphead[section][numbercommand=\headtext{section}~] \setupheadtext[de][section=Aufgabe] \def\task{\section{}} so if my document looks like \starttext \task \task \stoptext this should render to: Aufgabe 1 Aufgabe 2 (i hope the mailing list delivers html mail) And maybe somebody knows a cool way to do this: \starttext \task \task[Graphs] \stoptext ↓↓↓↓ Aufgabe 1 Aufgabe 2: Graphs thank you!
