Referring to all occurrences with IN COMPONENT
In the schema designer, you can refer to all occurrences of an object contained in a component list. To refer to all components in a component list, up to a given component, the word COMPONENT is used.
For example, the rule on the component Conclusion Topic needs to count all of the valid Topics up to, and including, Conclusion Topic.
The IN COMPONENT
expression can be used:
#Topic Field:$ = COUNT (Topic IN COMPONENT)
The above component rule works only if Topic is partitioned.
