I'll ask O'Neil to share some of the experiences: he has led this development.
We did try more than one approach; rather than a formal evaluation it was more
a case of "if X doesn't work let's try Y", until we hit on Jet which did the
business.

You mean in terms of bridging the API? We haven't really explored what's
feasible yet in terms of libxslt2 and libxml cooexistence. At the moment if
you've got data in a libxml tree you have to serialize and reparse to get it
into Saxon. I don't know if we'll ever be able to do better than that; I
suspect the overheads of doing it this way are lower than the overheads of
accessing the libXML tree node-by-node from the Java environment, but we'll
find out in due course.
