            "description": "Deletes a workflow node.",
            "parameters": [
                "nodeName"
            ],
            "actions": [
                { "action": "delete",  "path": "$.workflowDefinition.${p.nodeName}"}
            ]
        },
        {
            "name": "deleteArrayOfWorkflowNodes",
            "description": "Deletes a set of workflow nodes.",
            "parameters": [
                "nodeNameArray"
            ],
            "actions": [
                { "action": "eval",  
                "value": "${array:forEach(p.nodeNameArray, '${macros:deleteWorkflowNode(var)}')}"}
            ]
