7.9.3 - pja - Union for property choices not clear #27

Closed PalmJanssen closed 1 year ago

PalmJanssen commented 1 year ago

The JSON implementation for the union for property choices is not clear to me.

Does the referencing property exist in instance data? Or is it replaced by one of the properties 'option1' and 'option2'?
As understood the option1 and option2 properties can also be multiple (n>1). Does that also work?

Yes, the property whose type is a union does exist, and contains as value an object (that represents the union "value") with either property option1 or option2.

As understood the option1 and option2 properties can also be multiple (n>1). Does that also work?

Yes.
