Re: PROV-ISSUE-233 (paq-dm-and-accounts?): If not in DM, should there be some form of account support in the paq? [Accessing and Querying Provenance]

I think it's effectively already there.  When PAQ talks about a "provenance 
resource", that effectively *is* a bundle of provenance, which may have a URI, 
and about which provenance can be asserted.  I don't think more is needed.

A client was then able to sift through the container, and find whatever it was looking for, possibly multiple entity records for entity-uri in various accounts.  All that was possible without having to discuss accounts in the PAQ document.
