How to add perspectives to relationships?

[asos-alexwhite]

The language reference says

perspectives

The perspectives block is used to define one or more name/description perspectives for an element or relationship. See Help - Perspectives for how these are used.

perspectives {

...
}

My question is - how do you add a perspective to a relationship in the DSL?

This would clearly be a very useful thing to do when working with security perspectives, as attaching some security threats to a relationship would be very helpful.

The language reference tells me it can be done, but I can't find an example.

It works in the same way as for elements; for example:

user -> softwareSystem "Uses" {
    perspectives {
        "Security" "..."
    }
}

Thanks - I don't know why I couldn't get it working before, but now I can add the perspectives to relationships just fine.

User error I guess!
