message flow between Activities within a Pool 2 Years, 3 Months ago

How the Massage flow is happening between the Activities within a Pool. What i understood from the <MessageFlow> tag in XPDL documentation is, this can be used for Message Flow between the Pools or Activities which are in different Pools.
Which tag should I use if Activities are within the same Pool.
Thanks in Advance

If there's message flow between activities within a process, then you don't have a valid BPMN process. Message flow is defined to be between activities in two independent pools, or between two pools, or between a pool and an activity in another pool.

Hi Scott,
If so, what exactly DataField and TypeDeclarations are used for. If I am not wrong, These are used for storing the values(messages) and which are local to the POOL. I am in confusion state to understand what exactly these are used for.
Please help in this.
Advanced thanks.
Regards,
Naveen

TypeDeclarations are global for the entire XPDL package. DataFields are like the member variables or local variables of a process or an activity - that is they local to <WorkflowProcess> or <Activity>, not a pool. Messages can carry data from one process to another using parameters, not data fields, although I'm not clear on why a distinction was created between the two.
