Per,

Sorry if my solution seems old-school, but I had read the entire thread.

You answered the direct question of telling that the underlying
transformer has no such setting.  I tried to answer the next question by
indirection.  There are all sorts of ways to define a base directory,
and the one I have used in the past is what I described because it fit
more easily with our needs.  Your solution would take 10 minutes of
code, you said, and mine took maybe 5.  Which is correct depends a lot
on your application needs.

The interesting bit is that your solution and mine would both be placed
in just about the same place in whatever code one would write.  Since it
can't be done (by your statement) internally to the XSL parser, it would
have to be done in the wrapping code, no matter what the solution.

Passing an environment variable is quaint and maybe not very elegant,
but it does work.  I shared it because the original poster asked
specifically about passing system properties.  Since the JVM used to
pass the environment of the operating system in but no longer does, I
thought my contribution was pertinent.
