Omschrijf het probleem / Describe the bug

I might be misunderstanding what an OnderwerpObject is, but from what I understand from the information model it is used to link KlantContacten to objects such as Zaken (https://vng-realisatie.github.io/klantinteracties/informatiemodel/semantisch_model)

In the help text of the identificator fields however, examples are given that refer to a Natuurlijk Persoon (by using BSN)

Also since no enums exist for codeRegister, codeObjecttype and codeSoortObjectId, it is not clear what values those are capable of having

No response

Verwacht gedrag / Expected behavior

I think there should be enums for the mentioned fields, similar to PartijIdentificator:

I'm not sure what the values of those enums should be though, so this is up for discussion

Looks like it was copy-paste from the partij identificatoren documentation, as I undertand it the purpose is indeed to refer to resources in third-party systems, such as a zaaksysteem. There are not currently many hard constraints on how to do this, but here's one proposal we drafted for pointing to zaken in a ZGW API: Klantinteractie-Servicesysteem/KISS-frontend#808 (comment)

Note that that proposal is just a start, there's more details to flesh out, but in any case, I agree the documentation here is off.
