XML-dev is not dependable for me. I think this posting was lost.


FPIs cannot be assigned in someone else's namespace, the "owner" identifies
a naming authority, not an intellectual property owner. Assertion supported
with verbiage quoted from relevant ISO standards.

I'm sorry this is flat out wrong. ISO 9070 is very clear on the subject,
and I quote:

"3.10 Owner name: the portion of a public identifier that names its owner.
.... 13 The owner of a public identifier is not necessarily the owner of
the object it identifies"

and from the introduction:
"... and an 'owner name', which identifies the originator of the public

The whole point of owners (I can't quote the showe standard, unfortunately)
is to create domains of administration for namespaces, and sub-namespaces.
This just can't work if I'm allowed to make names in _your namespace_
without your permission, just because I'm citing your work. So either there
is a wording goof in 8879, or 9070 is making

I've never heard of this practice, and since it leads to a chaotic and
broken system of public identifiers, we should stamp it out to the extent
that it has been accepted.

IDN is not in 9070 rev 2, and thus is not suitable _de jure_; it is also
unsuitable _de facto_, since domain names can be reused by different
organizations. Unless Internet policies and 9070 have both changed, I think
this is also wrong.

>ISO 8879 says 4.223 owner identifier "The portion of a public identifier
>that identies the owner or originator of public text".

That definition conflicts with the 9070 definition, but in the context of
the public entity sets in SGML, the confusion of identifier owner and data
owner is understandable. When 8879 was written, the notion of needing to
assign persistent names to _other people's_ computer readable documents was
not foremost in anyone's mind.

This interpretation is explicitly contrary to 9070, though, and 9070 is
more recent, normatively cited by 8879, and edited by the same editor; so I
am inclined to prefer the 9070 reading. Also, the name assignment protocol
you suggest fails to achieve the list of goals in 9070 for the whole public
identifier standard, since it fails to provide a set of rules that will
guarantee that no colficting PUBLIC identifiers are ever assigned. The 9070
interpretation does provide such rules, based on hierarchical name
