Oliver and I have reviewed section 3.2.1 relating to the BP-94 proposal; the slightly modified test is listed below.

BP94-Proposed Text Change:

 

In case a composite task is pre-defined as such, the task model contains the definition of one or more sub-tasks. Composite tasks come with the following additional attributes:

·        Composition Type (parallel | sequential)

Composite tasks with composition type “parallel” allow multiple active sub-tasks at the same time; sub-tasks are not in any order; composite tasks with composition type “sequential” only allow sequential creation of sub-tasks in the pre-defined order (a second listed sub-task must not be created before a first listed sub-task has been terminated).

·        Instantiation Pattern (manual | automatic)

Composite tasks with instantiation pattern “manual” expect the “actual owner” to trigger the creation of pre-defined sub-tasks; composite tasks with instantiation pattern “automatic” are automatically created at the time the composite task itself turns into “in progress” status; (where composition type is “parallel,” all pre-defined sub-tasks are created at the time the composite task turns into “in progress” status; where composition type is “sequential,” at the time the composite task turns into “in progress” status, the first defined sub-task in the sequence is created; the next sub-task in the sequence is automatically created at the time its predecessor is terminated).
