Request to condense choice types into single value

[GinoCanessa]

For choice properties, did you consider encapsulating the value in a union-like type and having just one top-level property? So an example might look like this:

Patient
  Deceased
    Boolean
    DateTime

instead of

Patient
  DeceasedBoolean
  DeceasedDateTime

I've considered it, but haven't had time to sort out the serialization and deserialization handlers to support it.
