It's certainly possible in theory. However, I think a very considerable
amount of the work that's currently done at compile time would end up
being done at link time, so linking the modules dynamically for each
transformation might not give great performance.

I'm currently working on a different approach, which is to make sure
that all the unused variables, templates etc from imported modules are
discarded from the compiled stylesheet. This creates a few problems for
things like saxon:evaluate(): which actually confirms the reasons some
implementors were reluctant to put an evaluate() function in the spec.
