Sequence Diagram Titles

Does anyone know of a way to remove the title from a sequence diagram? I am referring to the rectangular box in the upper left of the diagram that has the text "sd " in it.
None of my other diagrams have titles like this, I use captions in my documents to give diagram titles.

Anybody tried to get rid of this?


Dear Merit,

The boxes are cannot be removed. According the UML 2.0 notations, all interaction diagrams (sequence diagram, communication diagram) must have this to specify the interaction (the frame).

Best regards,

Interesting, I did not realize that.
