Ira,
Thanks that seems to solve part of the problem, but what do we do with end
customers, e.g. a printshop?

Hi,
A whole lot of IETF protocols (e.g., SLP attribute names) use the
universal IETF convention of 'x-nnn-' as a prefix where 'nnn'
is the vendors decimal enterprise number assigned by IANA.
It's clean and simple and never ambiguous (no two vendors will EVER
have the same enterprise number).
Cheers,
- Ira McDonald

Well, again, I think it is challenging the elasticity of the main goal
which was to establish one authoritative list of STANDARD media sizes. In
an XML encoding I can picture distinguishing media name as belonging to a
"standard" vs. "private" naming authority. If we MUST accommodate this
goal in the compromise syntax, I guess I suggest a convention of the
"class" or "naming authority" such as
"vend-xxx"
where xxx could be the name of a vendor or customer.
Again, I believe it would be better to keep the media names in this list
we are collecting STANDARD and fairly SIMPLE.

Harry,
I think I have to agree with you on most points. In particular I like your
suggestion to change the name as the current name carries too much
semantic
connotations, which can easily be misinterpreted.
The one important issue I still see is whether we want to lay down some
rules for how to add "private names" which are not in our list, be it by a
vendor or by end customers.
