Andrew,
If I'm understanding you properly, the only major difference between the
business process workflow (the one I am writing) and the data integration
workflow you mention is that one requires human interaction, while the
other is handled by automated systems. Is that fairly accurate? If so

I don't think we need to worry about this for a while. It doesn't say

know). But, they have not given any indication of what version, which means
they probably won't remove it until the version AFTER 2012 (2014, maybe).
