EAI — There is no concept of process integration

There is no concept of process integration, to integration process models (e.g., B2B -> A2A, where a B2B activity initiates an entirely separate A2A either via one-way message or request/response). Even IDEF0 allowed that via the Call function. In fact, I think that using EAI already makes this document outdated, most energies are being focused on BPI). Activity graphs are the tip of the iceberg so to speak
