[NTG-context] separate publication lists for different publication types

[Eidenbenz Michael]

hi all,

is it possible to have separate publication lists for different publication types? 
eg. one list for the book, booklet, inbooks, manuals  and the other list for article, conference, periodicals?
I tried to define two different bibliography style files for each list, where I defined \setuppublicationlayout just for the desired types, but this doesn't work. either it gives me a blank line for an undefined record type or it takes the definition from somewhere else.

thanks, 

michael
