[NTG-context] xml/fo typesetting with ConTeXt/foXet?

Hi list! I am hoping that someone can point me towards some more information on typesetting FO (Formatting Objects) with foXet and ConTeXt. I've read the threads on the foxet mailing list (and I assume that's dead, last post in 2005), and the wiki provides pretty sparse information. There are some files listed in the manual, but it doesn't say how to load them (or I missed that part, very possible). I can parse my .FO file, but the content is just flowed into PDF, there are no line breaks, or headings, or anything-- it just strips out the xml tags. Thanks for any help/directions! Best, Mica
