BpmnValidationIssue : One problem found by deploy-time BPMN validation (backend/orvanta-bpmn/src/validate.rs). Warnings and errors share this shape and are told apart by severity.
The elements this problem is about — what an editor should mark on the canvas. Empty when the problem names nothing on the canvas (an unnamed unrecognized element, a whole-scope rule on the root process). Never the id of a referenced element that is missing: marking that would flag an innocent shape.
