Set to true to enable references to shapes outside the service closure.

Setting this to true means that all the shapes in the model must not conflict, whereas
leaving it at the default, false, means that only the shapes connected to the configured
service via {@link #setService(ShapeId)} must not conflict.

@param enableOutOfServiceReferences true if out-of-service references should be allowed. default: false
