UML sequence diagram ref without and sd

[StanleyNeoh]

Hello.

I am currently trying to draw a UML sequence diagram to show many if-else statements, similar to what you may see in a Command pattern.

Is it okay to use refs without a sd for every ref?

Thank you in advance

@StanleyNeoh Yes. In fact, you can also omit some of the ref frames as they don't seem to add much value. Show just a few and add a note to explain how the rest are done similarly.
