interaction frame

Question

Is there a way to draw a frame around a sequence diagram, like it is shown in the current uml specification on page 566 (section 17.2.4.1)

The notation for an Interaction in a Sequence Diagram is a solid-outline rectangle. A pentagon in the upper left corner of
the rectangle contains ‘sd’ followed by the Interaction name and parameters. The notation within this rectangular frame
comes in several forms: Sequence Diagrams, Communication Diagrams, Interaction Overview Diagrams, and Timing
Diagrams.

A simple group does not achieve the required result, because the instances are not included in the rectangle.

Comments

This would be fantastic, especially that we could get interaction overview diagrams in PlantUML.

Answer 1

Yes, please implement this!

Answer 2

Thanks for the suggestion!

With last beta http://beta.plantuml.net/plantuml.jar you can now have:

@startuml

mainframe This is a frame

participant alpha
participant beta

alpha -> beta: a1
beta <- alpha: a2

beta -> alpha: b1
alpha <- beta: b2
@enduml

It this what you are looking for ?

Comments

Yes, this works. Thank you!

can the space between the main frame and the starting place of the partcicpants be increased ? The current space is very minimal to differentiate.
