[NTG-context] about suppressing prefix in section number

Hi, Here are a few questions. 1. The output of \section{one} \section{two} is 1.1 one 1.2 two But is it possible to suppress the prefix chapter number like 1 one 2 two ? 2. When defining custom itemgroup, we can set each level using the predefined item headers, like n, r, 1, 2, ...., and it works fine. I am trying to use newly defined conversion, but I couldn't succeed. Is it possible to set an itemgroup using predefined item and custom made item head like \def\circlednum#1{\uchar{36}{95+#1}} \defineconversion[cnum][\circlednum] ? Thank you and Have a nice weekend. Best regards, Dalyoung
