You can use Text Annotations to provide additional information on the models for the reader of a BPMN Business process diagram. Text Annotations are displayed within an open rectangle attached to any symbol on a BPMN Business Process diagram by a straight line.

In System Architect, you add text annotations to symbols on a BPMN Business Process diagram by adding text to the Comment property within the Symbol tab of any symbol on a diagram.

Text Annotations do not affect the flow of the process.
