BPMN21 — Some of the descriptions in the bpmnElement column of the table are incorrect

The description in the bpmnElement column of the table for the Sequence Flow, Conditional Sequence Flow, and Default Sequence Flow elements is incorrect. default neither is an attribute of the listed elements, nor it is of type boolean. It belongs to the element referenced by the sourceRef attribute, and can either reference an element or be undefined (it cannot be false).
