• REST + JAVA
• I can start and stop activities in the context of multi instance and loops
• TBD: exact semantics

Exact semantics:

• with this feature it will be possible to make a sequential multi instance activity parallel for the lifetime of the newly created instances
• when an instance of the miBody already exists:
• instantiating an inner activity as a child of an existing mi-body instance will: create an additional concurrent instance in case of parallel MI and update the mi variables numInstances, numActiveInstance; increment the loop counter variable and set it on the new execution; throw an exception in case of sequential MI
• instantiating an inner activity will as a child of an instance higher in the scope hierarchy: create all scopes (including the miBody) as usual, create the mi-body execution structure as if it was entered via sequence flow (i.e. with parallel MI, there is always a concurrent execution even though there is only one inner instance), create the mi variables (nrOfInstances set to 1), create the loop counter variable for the first instance
