XSLT Optimizer and Deployment

I am writing an XSLT optimizer, basically stripping comments and extra
white-space from an XSLT document for production deployment.  I
thought, before I get to far into this if anyone has any suggestions.
I stumbled upon a blog post featuring Michael Kay, but did not find
the stylesheet there:  http://goo.gl/dzo6P

Thanks for any help.
My optimizer will perform a couple of additional steps:  set default
parameter values for production, make sure logging and other debug
steps are disabled, and so on...
