UiaML Core Properties

Explanation

The choice element enables us to model dynamic site navigation. It requires exactly one incoming link and has two or more exiting links. Due to the fact that exiting link aren't triggered by the user themselves the link type of exiting links is that of an event link.

The decision description must result in the deterministic choice of exactly one exiting link to be followed. The choice has to be based on information available within the system. By specifying the information sources (most of those will be CAE's that had some interaction with the user) the modeler can verify that information indeed is available and accessible within the system, and the developers will be very thankful for this kind of information.

Since the information sources might not be known / modeled at the time that the choice element is modeled the decision base information might be one of the properties one sets at last.
