Hi,
My opinion is that we're talking about slightly different things.
Path in the sense Freek defines it seems to represent a "finalized"
object while the way John describes it is closer to an "unfinished"
object that we would find in a service request.
I think both approaches have value, and are in fact very close but
maybe we would like to to differentiate between them?
