Acute API - Appointment.Type and DocumentReference.class

I’m sold on using SNOMED codes with a suggestion we have that spreadsheet centrally maintained (I want to look into FHIR value sets to see if it can provide lookup service for this)

How would we get agreed an published across the UK?

It would be very useful with many (NHS) organisations going paperless to start getting the metadata for Documents in sync (presumption is we will go to some form of cross enterprise document sharing at some point). Getting it wrong (now) can be very costly with extensive rewrites, complex mapping exercises or even document formats - e.g. storing documents as TIFF’s when we know the probable standard will be PDF (and CDA).
