Snapshot Cardinality not correctly inherited. #2770

In the following profile there are a few issues in the profile itself, but the snapshot generated by Simplifier seems incomplete.

The author of this profile has incorrectly set the allowed cardinality for Address.extension:language to 0..1 while the used extension for language has a top level cardinality of 1..1.

Regardless of the profiling errors in the profile Simplifier renders the tree as follows:

The cardinality for the Address.extension:language is rendered correctly as 1..1, however the cardinality for Address.extension should also be rendered as 1..*. Also when uploading this resource without the IG publisher snapshot to Simplifier and downloading it with a Simplifier generated snapshot does not fix the cardinality for Address.extension.

Forge handles this perfectly and updates all incorrect cardinalities.

Ah so we should "calculate" the correct cardinality of the extension element, which I think we do, but maybe not for the use case for the combination of root cardinality and "slice member" cardinality. Is this fixed when the author corrects his "mistake"?

Besides, you can argue if it's true that when an extension has a root level min cardinality of 1, automatically the extension slice intro should also be 1. This is different behavior than other slices I believe. Or am I mistaken?

Unfortunately, fixing the authoring mistake does not solve the issue. It is still rendering the Address.extension as 0..* instead of 1..*

There is a small side note here https://hl7.org/fhir/elementdefinition.html#interpretation, which says:

"or less commonly, make the extension mandatory (min=1) - i.e. if the extension is referenced in a profile, it must be marked as mandatory."

Of course, an extension cannot make itself mandatory, but reading this fragment it means that if a profile author uses an extension in a profile, then this cardinality means "the minimum cardinality of the extension within the profile", which boils down to the minimum cardinality of the slice for that extension.

I am quite sure we've not covered this exotic corner case.

Yes, that rule I knew! But that doesn't automatically mean that the extension slice intro should also has a cardinality of 1 right?

But maybe this is different for extensions.
It would be weird to say in the extension slice: "Extensions are not required, but if you want to send them , send at least this one"

That would be totally normal for other slices. So maybe we should create custom extension logic here, which I am not a fan off.

Copied the profile here in case it gets deleted or fixed on simplifier:

Postal addresses are often used as proxies for physical locations (also see the [Location](location.html#) resource).\r\n\r\nSpecial remarks for KMEHR users:\r\n\r\nNote when .use and .type are used they SHALL use the FHIR defined valuesets as per their required binding level in the FHIR specification. In a KMEHR address, the use was defined by CD-ADDRESS but those values can be found in the FHIR valueset.\r\nKMEHR values 'careadress', 'other' and 'vacation' are not directly present in the FHIR address-use table but can be mapped to the value 'temp' in FHIR. In those cases, it is RECOMMENDED to also add a .period.\r\nIn KMEHR, an address might be expressed using free text or a totally structured approach where the streetname and housenumber are put in separate fields. FHIR prefers a more pragmatic approach where the ‘text’ element is used to print on labels. Also, streetname and number are not separate fields as in KMEHR but in a structural approach are given as one or moren ‘line’ elements. It is however RECOMMENDED to use the Streetname, Housenumber and Postbox extensions to express them seperately.\r\nNote the FHIR address also allows to optionally define whether the address is a physical, postal or ‘both’ address using the .type field.",

Postal addresses are often used as proxies for physical locations (also see the [Location](location.html#) resource).\r\n\r\nSpecial remarks for KMEHR users:\r\n\r\nNote when .use and .type are used they SHALL use the FHIR defined valuesets as per their required binding level in the FHIR specification. In a KMEHR address, the use was defined by CD-ADDRESS but those values can be found in the FHIR valueset.\r\nKMEHR values 'careadress', 'other' and 'vacation' are not directly present in the FHIR address-use table but can be mapped to the value 'temp' in FHIR. In those cases, it is RECOMMENDED to also add a .period.\r\nIn KMEHR, an address might be expressed using free text or a totally structured approach where the streetname and housenumber are put in separate fields. FHIR prefers a more pragmatic approach where the ‘text’ element is used to print on labels. Also, streetname and number are not separate fields as in KMEHR but in a structural approach are given as one or moren ‘line’ elements. It is however RECOMMENDED to use the Streetname, Housenumber and Postbox extensions to express them seperately.\r\nNote the FHIR address also allows to optionally define whether the address is a physical, postal or ‘both’ address using the .type field."
