* Variables in internalExecution are handled this way:
* - Process (global) variables are all in one VariableScope. This variable Scope always exists,
* even if it is empty.
* - Activity (local) variables are in a second variableScope. This variable scope only exists
* when there are local variables.
*
* Methods getLocalVariables and getGlobalVariables are provided to have access to global and
* local variables of this execution.
