Type Attributes in Rules
Specialized rules must have a type attribute so that they can be selected from drop-down menus throughout the application. Each specialized type also has its own set of input and output variables and, optionally, a return value.
In each area where you can select a rule, you are limited to choosing (or creating) rules of the type that is appropriate to the feature. For example, in the Edit Policy page, the Policy Owner rule drop-down only lets you choose rules of the type "PolicyOwner".
The rule type is shown in both the Rule Editor, and in the rule’s signature in the Debug pages.
