Intentions are high-level goals at various levels of the plan, an annotation specified by the designer that supports tasks such as critiquing and modification. Intentions are temporal patterns of provider actions and patient states, at different levels of abstraction, that should be maintained, achieved, or avoided. Conditions are temporal patterns, sampled at a specified frequency, that need to hold at particular plan steps to induce a particular state transition of the plan instance. A plan instance is completed when the complete conditions become true, otherwise the plan instance's execution suspends or abort. Aborting a plan instance is usually due to a failure of the plan or a part of it.
All conditions are optional.
The plan body is a set of plans to be executed in parallel, in sequence, in any order, or in some frequency. Only one type of plan is allowed in a single plan body. Concurrent plans can be executed in parallel or in any order. Table 3 summarizes the dimensions of the two plan types. The continuation condition specifies the names of the plans that must be completed to proceed with the next steps in the plan.
