[NTG-context] Best strategy for ConTeXt to ePub update

Hi all, While ago I wrote a book (http://sstv-handbook.com/) in ConTeXt and I have started to thinking about possibility to export also ePub and xHTML besides the PDF version. Few questions: 1. What is current support of ePub, will it export pictures automatically? 2. Do I need to rewrite source code to use those verbose \startsXXX of every element (paragraph, item,...) or is there any simplier way how to handle sources as they are now? Regards, BruXy
