Topic: answerOption vs initial

Hi everyone, I was looking at the R5 questionnaire and was wondering why the answerOption has less options (6) than initial (12) when from my understanding, they should go hand-in-hand?

Not necessarily. Some datatypes don't make sense as a set of options to pick from, but fine for an initial value.

thanks for the answer. Could you please provide me an example so I can better understand this?

Very simple example - it makes sense to be able to specify an initial (default) value for a boolean - i.e. 'true' or 'false'. However, we don't allow defining the allowed options for a 'boolean' because that's built in (the only options are true and false).
More complex - we don't have a use-case for providing a constrained list of 'decimal' or 'quantity' values for a user to choose between. However, we do have use-cases for defining initial/default values for these.
Lloyd McKenzie (Apr 04 2022 at 13:05):
In short, we don't include a data type for 'option' unless we have concrete examples of how/why a system would constrain that type as a selectable choice.

Great! Thanks for the answer!
