We discuss ambiguities and inconsistencies in the Business Process Model and Notation (BPMN) 2.0 standard regarding the semantics of event-based gateways, and instantiating event-based gateways in particular. We suggest to use instantiating parallel event-based gateways to model asynchronous process behaviour and to clarify the BPMN standard accordingly. We further discourage from any other use of instantiating event-based gateways, and call for a clarification of the semantics of event-based gateways in general.
