Dear Alan,

Thanks for your comments. We have entered it into in our tracker as
ISSUE-552. You can check on our internal discussion at
https://www.w3.org/2011/prov/track/issues/552

As to not bombard you with emails, we'll discuss this internally and
get back to your either with clarification questions or hopefully a
resolution of the issue.

Thanks for taking the time to look at prov.
Paul
