FHIR EOB : priority attribute error

[rohinigolesar]

I was validating Davinci FHIR EOB resource against FHIR validator and I get an error for Priority attribute "Found a reference to a CodeSystem 'http://terminology.hl7.org/CodeSystem/processpriority' where a ValueSet belongs". The system specified has code and display still gives an error

This is an error with R4 model itself and we need to suppress this error. Please refer https://chat.fhir.org/#narrow/stream/179283-Da-Vinci/topic/EOB.20Priority.20Error
