Yes, I meant they were distinct in terms of support in openEHR - that (b) is perhaps easier to support than (c). But you are right that (c) is a superset of functionality that is currently supported by CDA and hence to covering CDA fully would cover (b) and (c).. > required to be faithfully displayed by everybody.

I agree that the narrative form "wins" but I think the HL7 people would be horrified by the thought that CDA structured content was generating textual content which could then be secondarily changed - it is a clearly broken use case and noone would design new software that way - but I understand that there are some legacy systems in Australia that do it this way and that Ocean needs to come up with solutions around this. But I am quite keen that solutions to this particular outlying use case don't impact on solutions to (b) and (c) unless we all understand the ramifications. Andrew
