Is it a bug if a symbol in the UML diagram is not defined? #944

Closed kjw142857 closed 6 months ago

If a symbol in the UML diagrams in the DG is not defined, is it a bug? An example would be the "X" after the activation bar in the sequence diagram. In addition, do we need to elabourate on the limitations of PlantUML, or is it NotInScope? (e.g. the lifetime of an object extending to the end of the diagram, even if there is an "X")

@kjw142857 You may use UML notations in the textbook, without defining them again. That's the benefit of using a standard notation.

In addition, do we need to elabourate on the limitations of PlantUML? (e.g. the lifetime of an object extending to the end of the diagram, even if there is an "X")
