Hi Rupert, Thanks a lot for the detailed answers. Let me play a little bit further before I ask additional follow-up questions.
As far as demo is concerned, I am interested in eHealth demo as it covers lots of items from my questions. At present, the Java code for it is missing. Is it possible to restore Java code for eHealth demo in 0.12 branch?
