Does JSON and XML support is provided with camunda-bpm-workbench based on bpmn-io?

Due to some new features of camunda 7.8.0 , does any support provided inside camunda modeler or workbench to use the following datatype from generated user Forms.

User Forms is only capable of few dataTypes (string, enum, integer,custom etc…), Do Json or xml datatype can be added with predefined datatypes ?

I’m not exactly sure I understand your question. Could you add a few examples to clarify your use case?
