Current state of STP IM? [message #605710]

Hi,

I am wondering what the current state of the STP Intermediate model is?
Is the version on the Wiki [1] up to date? If so, I am curious why a
step is part of a process, but the transition is not? And, on the other
hand, why there is only one edge between a step and a transition with
cardinality *. In many other standards (like UML activity diagrams)
there are always two edges between a node (=ActivityNode in UML) and a
transition (=ActivityEdge in UML) specifying that a transition has
exactly two ends (cardinality of 1 at each edge)?
How are the conditions at TransitionUnderCondition specified? Are these
boolean conditions connected with AND, OR, XOR and NOT? Or is this open
to each implementation (BPMN, SCA, JBI, etc.)?
Do only Transitions have ObservableAttributes? How about attributes that
are specified at a step?
Does a process or a step has no owner, but only a service?

Looking forward to your answers,
