  "code": "apply",
  "comment": "The result of this operation is a CarePlan resource with a single activity represented by a RequestGroup. The RequestGroup will have actions for each of the applicable actions in the plan based on evaluating the applicability condition in context. For each applicable action, the definition is applied as described in the $apply operation of the ActivityDefinition resource, and the resulting resource is added as an activity to the CarePlan. If the ActivityDefinition includes library references, those libraries will be available to the evaluated expressions. If those libraries have parameters, those parameters will be bound by name to the parameters given to the operation. In addition, parameters to the $apply operation are available within dynamicValue expressions as context variables, accessible by the name of the parameter, prefixed with a percent (%) symbol. For a more detailed description, refer to the PlanDefinition and ActivityDefinition resource documentation",
