Some elements are best described by their properties. Their title is derived based on the elements they relate to and will be changed if their related elements change. You can spot such derived title by its brown color. At any time, you may place your cursor in it and type to override it. The color will change to black and the title will no longer be updated when a related element changes.
In general, {x} is an expression that will be replaced by the name of the corresponding element in the role x. In the previous figure, we can see that the derived title for security objectives is determined by taking the name of their class, adding a space, and then taking the names of their target TOE elements.
The uppercase expression {X} will be replaced by the title of the element in role x. So this works similar to its lowercase sibling, just that the uppercase uses the title instead of the name.
If there are multiple elements in such relationship, itemis SECURE will join them, with a ", " between each. For example, this may be the case for the technologies of a channel. {t} may then be replaced with tcp, https, given these are the names of our channel’s technologies. For some elements, this may get too long, so that the expression {d...} will help out: if there are more than one related elements, it will simply append ", ..." to the first element. That makes the title much more readable in some occasions.
