Just to clarify.
When the BPEL folk say "human interactions" they mean between
interactions between humans and systems (H2S). This is what BPEL4People
sets out to deal with.
This is a separate matter from interactions between humans and humans
(H2H), the domain of Human Interaction Management
<http://human-interaction-management.info> (HIM). Such work is
collaborative, innovative, and adaptive - and cannot be supported with a
language such as BPEL, no matter how it is extended. All mainstream BPM
languages, including graphical notations like BPMN, are based on
carrying out steps in a pre-defined sequence, which is not how humans
work together.
