[NTG-context] Hide section content

Hi, I have a tex file that looks like follows: \startsection[title=...][review=yes] ... \stopsection \startsection[title=...][review=no] ... \stopsection When I compile the document with --mode=review, I want that all sections that have `review=no` should not be displayed. What is the best way of achieving this? In particular, can we have an option that'll let us say: \setuphead[section][placebody=hidden] (analogous to placehead=hidden). Aditya
