codeSelector
A code selector constructs a Code value inline. The code string identifies the code within the specified code system. An optional display clause provides a human-readable label.
Examples
Inline code without display
Code '44054006' from "SNOMED-CT"
Inline code with display label
Code '4548-4' from "LOINC" display 'Hemoglobin A1c'
