How to render uriorcurie as RDF node?

[Natureshadow]

I want to add an attribute to a class that holds a reference to other RDF nodes, if rendered as RDF/JSON-LD.

The type uriorcurie always seems to be rendered as xsd:anyURI. The objectidnetifier type can only be used for internal URIs inside the model. I want my instances to have a URI or CURIE in this attribute, and I want it to be rendered as RDF node in RDF representations.
