Using Sequence Diagrams elements

[MattAdamson]

Has anyone much experience reviewing the elements in sequence diagrams such as fragments and parts of fragments. I can't see an easy way to extract this, a fragment seems to be an Element type within the object model.

I've worked out how to find the connectors for a specific sequence diagram and detail such as the lifecycle attribute i.e. whether it's new or destroy and also information part of the message such as the parameters passed.
