Yep. Most transformation engines have pretty bad startup times. Though
if your transformations are taking >10 seconds it probably doesn't
matter. Xalan has a bit slower transformation speed than Saxon but has a
horrible startup time (probably because it is so huge). Running it
in-process solves that problem, of course.

Thanks.

The Python bindings are for Xalan 1.1. The CVS version works correctly
with Xalan 1.2 but hasn't been extensively tested. I can send you a
binary if you are interested.
