        <p>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.</p>

        <p>For a more detailed description, refer to the PlanDefinition and ActivityDefinition resource documentation. Note that result of this operation is transient (i.e. none of the resources created by the operation are persisted in the server, they are all returned as entries in the result Bundle(s)). The result effectively represents a proposed set of activities, and it is up to the caller to determine whether and how those activities are actually carried out and/or persisted.</p>
