Yes (and No).
Yes, because it's coded like you wrote;
(No, because "exclusive choice" is a workflow pattern corresponding to
OpenWFE's <if> expression).
If you want to "chain" participants you have to write things like :
<sequence>
<participant ref="a" />
<participant ref="b" />
<participant ref="c" />
</sequence>
The participant expression is about sending the workitem to one
participant. (though the expression map could list a participant as a
set of other participants, but the engine itself (via the
ParticipantExpression) doesn't care about such a finesse).

Yes, of course.
'field-ref' and 'variable-ref' exist since before the "$ notation",
maybe I should remove them, but they are quite straightforward.
