I never got a chance to test performance. The main benefit when I made the 
change was ease of debugging :)

I plan to move most of my code from XSP pages to transformers though. 
Currently I'm inserting my dynamic data into my mostly-static pages very 
early in the pipeline, thus undermining the excellent caching abilities of

I figured it would be compatible in the near term, but with some of the 
more radical ideas I've seen proposed (flowmap), I thought that down the
