I could imagine many users might specialise the "used" property to
express more precisely how an entity was used, e.g.

taverna:2613
  a prov:ProcessExecution;
  mywf:usedValue taverna:676.
mywf:usedValue rdfs:subPropertyOf prov:used.

Does this make sense?  Assuming we have no power to stop this being
done, does it have a different meaning to ascribing a role using the
Role class?

Thanks,
Simon
