Thanks Graham, very clearly put.

So in principle at least then, it may be possible to make statements about
the arc instance, if this were identified by means of the attached nodes -
an odd sort of {URIa & URIb} identifier. Hmm - but what happens if there are
two arcs of the same type between node a and b (which I *think* would be
legal). bArcs anyone?

As far as my app goes, I'm just going to forget about this angle for now ;-)
