 The Scheduled Execution interface exposes individual <<model-partition, model partitions>>.
 A scheduler provided by the <<importer>> can control the execution of each model partition separately.
 In some ways the Scheduled Execution interface has similarities to the Model Exchange interface: the first externalizes a scheduling algorithm usually found in a controller algorithm (see <<fmi-for-scheduled-execution>>) and the second interface externalizes the ODE/DAE solver.
