Hi Gerard, I agree with most of your comments and in principle that "most post-coordination (using modifiers in Snomed-space instead of Archetype/Template space) must end", this amounts to heresy in a UK context and I think we should be prepared to regard David Markwell's Grey Zone as a contested area for some time. I think we could waste a lot of energy in trying to reduce the grey zone and might be better served by allowing dual-representation in both openEHR paths and Snomed post-coordination, and concentrating our efforts on the clearer areaswhere one approach is obviously better than the other. I would rather present Snomed-openEHR as the productive marriage of 2 noble families, whose sum is greater than the parts, whilst accepting that there will remain on-going jockeying for position in the 'border lands'.
