We found that Inferno US Core MustSupport test on requiredBinding slicing only verifies coding.code. It shall also verifies coding.system.
One example is that Observation SDOH Assessment profile in US Core 5 has slicing on Observation.category using requiredBinding http://hl7.org/fhir/us/core/CodeSystem/us-core-tags|sdoh. Observation Screening and Assessment profile in US Core 5 has slicing on Observation.category using requiredBinding http://hl7.org/fhir/us/core/CodeSystem/us-core-tags|sdoh.
Without coding.system value, MustSupport test could incorrectly pass MustSupport test using observtion having not desired sdoh coding.
