The IG Publisher is creating two Implementation Guide resources with FHIR version 4.0.1 in its packages, which both have references to non-existing extensions or codes.

The one IG resource (e.g. package/ImplementationGuide-hl7.fhir.us.core.json) refers to non-existing extensions in the http://hl7.org/fhir/tools/* domain, including:

• http://hl7.org/fhir/tools/StructureDefinition/ig-parameter
• http://hl7.org/fhir/tools/StructureDefinition/resource-information

The other IG resource (e.g. package/ig-r4.json) uses a number of codes which are not in the corresponding ValueSet http://hl7.org/fhir/ValueSet/guide-parameter-code:

• copyrightyear, releaselabel, path-expansion-params, active-tables, apply-contact, apply-jurisdiction, apply-publisher, apply-version, show-inherited-invariants, usage-stats-opt-out, excludexml, excludejsn, excludettl, excludemap, excludeexample, generate and more

Both issues make it impossible for other tools to process the Implementation Guide resources properly. Example output from the .NET Validator can be seen by hitting Validate on this snippet: https://simplifier.net/snippet/wardweistra/30 (free account needed for Validate).
