Interesting point, and it certainly is a solution for the case of the
patient records. For some other stuff like  "nice-to-have but better leave
out if not required" (calibration) it is not an options. 

I see the problem in the fact that this required decryption logic on the
client side (but I may be wrong here, correct me please). It is an
attractive feature for the hospitals to use the XML format to display
customized reports; is it possible to transparently tell the browser "get
your encoding if you can"?
