False Warning Message Validating US Core Vital Signs

[jjathman]

Three warnings are produced from a valid US Core v6.0.0 blood pressure vital sign:

None of the codings provided are in the value set 'US Core Vital Signs ValueSet' (http:https://hl7.org/fhir/us/core/ValueSet/us-core-vital-signs|6.0.0), and a coding should come from this value set unless it has no suitable code (note that the validator cannot judge what is suitable) (codes = http:https://loinc.org#85354-9)

Here is an example taken directly from the US Core imp guide.
