[NTG-context] project structure simplification ?

Hi, when there is only one product, only one environment-style (but lots of component) in a project, is it necessary to start the files with these respective lines ... \startproject the_project \startproduct the_product \startenvironment the_style ... or is it sufficient for referencing to call only the file the_project.tex, the_product, the_style ? [asking for both, MkII and MkIV] Steffen
