Topic: RatioRange and CodeableReference in choice types
Lee Surprenant (Dec 08 2021 at 13:51):
R4B introduces new data types RatioRange and CodeableReference, but the list at https://build.fhir.org/branches/R4B/datatypes.html#open is not updated to include them.
RatioRange is already used as a choice type in Ingredient, so I assume they can both be used as extension values and that list should be updated to include them.

Additionally, wherever the conformance resources (e.g. the ones you get from https://build.fhir.org/branches/R4B/downloads.html) list the set of allowed types, I think these two new types should be added.
Lee Surprenant (Dec 08 2021 at 14:00):
I also noticed something unusual while looking into this one:
Task.input.value[x] (https://build.fhir.org/branches/R4B/task-definitions.html#Task.input.value_x_) and Task.output.value[x] seems to enumerate all the different allowed types. Should those just be an "open" types (*) instead?
For example, like: https://build.fhir.org/branches/R4B/elementdefinition-definitions.html#ElementDefinition.defaultValue_x_
Interestingly, it seems like the "open" choice types end up with the expanded list of types in the actual conformance artifacts, so its just some display sugar I guess.
Both cases are missing the new data types.
Lee Surprenant (Dec 08 2021 at 17:49):
Another spot that probably needs changing if the new types are allowed in "open" choice types: https://build.fhir.org/branches/R4B/extensibility.html#list
Lee Surprenant (Dec 08 2021 at 17:50):
Also, I've always wondered, is that list different than https://build.fhir.org/branches/R4B/datatypes.html#open ? Maybe better just to maintain that list in one spot?

I've opened FHIR#34453 for this one.
Grahame Grieve (Dec 14 2021 at 05:11):
fixed in R4B and R5
Grahame Grieve (Dec 14 2021 at 05:11):
the code maintains it in one place internally
Lee Surprenant (Jan 24 2022 at 22:15):
looks like this change will need to be backed out for R4B based on the new resolution posted to https://jira.hl7.org/browse/FHIR-34453 ...
Lee Surprenant (Jan 24 2022 at 22:23):
but I'm confused about how we could say its not an allowed choice type when its explicitly listed as a choice type in https://build.fhir.org/branches/R4B/ingredient.html
Lloyd McKenzie (Jan 25 2022 at 00:37):
Sorry, it SHOULD be a choice type. It can't be an extension type. We don't have to worry about choice types breaking anything because the only place they can be used is in the new/changed resources.
Lee Surprenant (Jan 25 2022 at 12:31):
ah, that wasn't clear to me from the resolution text at all. agree it makes sense, although
it sounds like a fun one given that grahame mentioned above that the two lists currently come from a single place
