Which of the following cannot be used with Declarative rules

In EMC Documentum's business process/declarative rule framework, a Declarative rule ties a condition (a 'Circumstance' template used elsewhere for conditional docbase configuration) to an action, but Circumstances specifically belong to a separate Documentum configuration mechanism (used for docbase config objects, not workflow rule triggers) and cannot be referenced inside Declarative rules. Agents, Functions, and FlowActions are all valid building blocks that declarative rules can invoke to perform work or route the process, which is why they're excluded from the 'cannot be used' answer.
