As I mentioned in private mail to Larry, I do not think that a document
whose publisher in no longer valid should be supported, unless that
document is placed in the public domain. A document without a publisher
(owner) cannot be guarenteed in any sense, since the guarentee of identity
is a function of the publisher.
So, if the publisher is the maintainer of the meta-information associated with
the document, (where does it live, who maintains it, etc.), and the
publisher goes out of business, then the document is no longer maintained
by anyone.
Who is the authority of the information of and about the document if it
has no publisher? Without any authority, there can be no guarentee of
identity.
I believe that this presupposes that there is some authority which maintains
the meta-information for documents in the public-domain. Volunteers?
I do not think that there was ever any assumption that the URN be a
permanent identifier. Rather, a URN must never be reused.
