Re: hadMember and wasInfluencedBy

I don’t think the errata statement should mention the OWL, since it is non normative and will soon be updated.

How about: https://github.com/timrdf/prov-wg/commit/52683ab01c1900efc0053405f08986c46e531bf1
it follows the pattern of the previous errata.

If okay, then Ivan can put https://github.com/timrdf/prov-wg/blob/master/errata.html at http://www.w3.org/2011/prov/errata.html
If not okay, fork it and propose the change.

My notes for the change process are at https://github.com/timrdf/prov-wg/wiki/PROV-errata
