Special Request only for the POST /api/policy-hub/policy-content endpoint:

Additionally to the generic structure - the support of "OR" constraintOperand for usage constraints are not supported for now.
Since this is in general allowed but not used by catena-x; i suggest instead of deleting the code to comment out the option to set an "OR" connection.
Note: access policies with an "OR" connection are still allowed (as shared above)
