[NTG-context] Comments and marks in PDF

Hi All! Adobe Acrobat Reader have special feature, called 'review'. So people can leave marks or comments in PDF file and save them. But AFAIK this can only be done with PDF files generated by Adobe Acrobat Pro. Is there any way to do something similar with files generated by ConTeXt? Basically, I need to pass my work through review process and people often request to add marks directly in files the are looking at. As they are using Adobe's reader exclusively, it would be great to use it's built-in features. -- Best Regards, Oleg Kolosov
