Hmmm, I think this is mostly covered by 
http://dvcs.w3.org/hg/prov/raw-file/tip/paq/prov-aq.html#retrieve-provenance-information-for-a-resource 
  (section 4.1.2).

This is the bit that I have trouble with.  What is this "account id"?  I think 
it's really inappropriate to introduce it as a concept in PAQ because it's been 
dropped from DM.

There is nothing in the specification that *prevents* you doing any of this, but 
if the notion of account isn't part of the provenance model it is bound to be a 
"private use" convention (which may become widely used and a later candidate for 
standardization).

I think an appropriate way forward here would be to prepare a separate document 
that covers the concept of accounts, account IDs and service extensions to 
access provenance keyed by account.  This could be a candidate for a WG NOTE 
(which we were told at F2F the WG may choose to issue without reference to the 
charter).

Which leaves me still inclined to close this "wontfix".

Generally, I think we should now be looking to remove material from the documents rather than add it.
