I found that the Kawa scheme interpreter (the one on top of which the
SENG DSSSL engine was being written) has been taken by Per Bothner
from Cygnus. Bothner rewrote the original code, extended it, but
it looks like it kept the DSSSL stuff. This new implementation of
Kawa byte compiles directly to java byte codes (some people were
talking about jade loading byte codes instead of having to process
the stylesheet everytime). It looks like the internals are well
documented 
(as oppose to jade's). So if somebody wants to implement a DSSSL engine
in java, this is worth looking at. (Or better if somebody can
rescue SENG). Take a look at http://sourceware.cygnus.com/kawa.
