My apologies for neglecting this, especially as I've been one of the
critics of earlier versions.

Looking at the version that accompanied the message I'm responding to.
(For clarity, I copy that part of the message below.)  The future uses
of reso URNs are still rather unformed, but that is quite reasonable
that this stage.  Clearly, you've put thought into how you would use
URNs.  And I think that is sufficient to approve this proposal.

I would suggest you give the text a final careful editing.  E.g., it
contains 'This link shows the "Property" resource', but no link is
