C2MS13 — Add a Participant Chain Concept to Notification Messages

For all data-related messages (mostly notification messages, but could be some response messages), consider adding an array as a Participant Chain... what component or resource was involved in producing the data... probably would be String for the name, a Typed Varialble, plus a time-tag. Typed Variable would allow it to be a digital signature. This has some oerlap with both Participant in TDM and Originator in NDMs.
