Kids First historically dictated age to be in days specifically to remove the need for handling units in the dataservice, but FHIR Age is a quantity that always has a unit attached.
Kids First may choose to continue to request days from investigators (alternative is to put another column for the unit into the data template), but the FHIR server model doesn't need to care anymore. I think it would be very reasonable to expect any downstream UI to be able to relate ages to each other regardless of unit.
So maybe we should remove the mention of days from the field description?
