I'm struggling with the notion of scratchpad.. From the SMART app's perspective, it is just telling the EHR to do something. It's more EHR internal process whether the action will be reviewed in a scratchpad before finalizing, or whether it will be immediately applied etc. Granted, it was myself, Josh, and Isaac who sat down and came up with the scratchpad., but now I'm having second thoughts In fact I'd even say, the messages should be fhir., and a separate fhir. message group described in 1.8.4 doesn't merit implementation.
