Topic: Cardinality of 'source[x]' in Consent
Niek van Galen (May 01 2019 at 14:19):
We have a Dutch Functional model of TreatmentDirective (based on Consent, see here: https://simplifier.net/NictizSTU3-Zib2017/ZIB-TreatmentDirective), it deviates from the FHIR Consent resource in a broader .source that refers to multiple AdvanceDirectives (also based on Consent, see here: https://simplifier.net/nictizstu3-zib2017/zib-advancedirective).
For instance: two AdvanceDirectives can be needed to substantiate one TreatmentDirective. In the FHIR Consent resource, the cardinality of 'source[x]' is 0..1. Would there be objection to change the cardinality to 0..*?

It's not possible to have a polymophic element (one ending in '[x]') that repeats. If there's a need to specify multiple sources, we'd have to change the structure so that an outer repeating element contained the polymorphic element.

@David Pyke ?
David Pyke (May 01 2019 at 14:33):
We can definitely have a look at allowing multiple sources via a change but that is a significant variation from Consent that we've worked with to date. Can you open a CR so that we can review it during the WGM?
Niek van Galen (May 01 2019 at 14:44):
Thank you both. I will do that and ask @Alexander Henket to explain further at the WGM if needed.

I would prefer we change source[x] to simply source as a Reference. Thus it could be 0..*
