But if the forms contain real data which is changing with each service (as 
real data almost inevitably does) you cannot cache anything and your 
transform process must be run for every service. If you are daisy chaining 
several transforms (particularly if you are reparsing at each step of the 
daisy chain) the overhead becomes huge and the response time to the user 
unacceptably poor.

I've done a lot of work over the last few months on improving the performance 
of dynamically generated pages transformed with XSL-T transforms, and I know 
the performance hit.

Having said all that, I would be extremely interested in seeing your
