Link Note to Internal Documentation on Sequence Di

[Barrie Treloar]

http://www.sparxsystems.com/uml_tool_guide/modeling_with_uml/linkingnotestointernaldocu.html

Shows me how to create a note and link it to features by for a Class Diagram.

I want to do the same thing but on a Sequence Diagram - so I can drop the documentation of a method onto the diagram.

I dont appear to be able to do this.

Is this not supported?

Cheers
