According to the UML 2 spec, I should be able to represent a Singleton in a sequence diagram.
I can't in Star UML. Does anybody know a free UML tool which can do everything in the UML2 spec?

Just an update on this. Star UML does provide some support for representating classes as singletons. you can select the "Apply Pattern" and then select the singleton pattern. Pretty cool. But the representation is that the class gets a self reference. this can look a bit clunky and I'd much prefer the "1" notation in the right hand corner of the class. This is much neater.
I can't get this. Any ideas?
I have also tried another tool: Software Ideas Modeller which looks really good but can't get this "1" notation on that either.
Does anyone know any free tools I can get this on?
