I'm struggling a little bit to understand all the differences in the profiled ImmunizationRecommendation resource and the R4 version. For instance, forecastStatus, forecastReason, and dateCriterion > code as listed on the "Differential" tab look nearly identical to R4 – is it just that the terminology binding strength was updated from "example" to "extensible?"

Is it possible to highlight these differences more clearly, or this just a product of the IG format?

I have a similar question about doseStatus in the ImmunizationEvaluation resource.

P.S. At the risk of being nitpicky, I notice a white space difference in the names of the value sets as listed in the structure view of this IG vs. R4 (e.g., "ImmunizationRecommendationStatusCodes" vs. "Immunization Recommendation Status Codes"), though the "Reference" links in the "Terminology Binding" section below it don't have any white space characters in either this IG or R4. I first wondered if that causes the IG authoring tool to call out those elements as diffs until I noticed the binding strength difference....
