Alexey Melnikov (APP AD) has provided many useful comments
on PA-TNC and PB-TNC. One issue that he has raised is
whether Expert Review should be required for IANA registration
of vendor-specific values in the NEA registries and, if so,
what the expert guidelines should be. Alexey has asked the
NEA WG to reconsider and discuss this matter. Therefore,
I'm raising this topic on the NEA list and cc'ing Alexey.
The text in draft-ietf-nea-pb-tnc-05.txt on this matter
is in section 7.1:
For all of the IANA registries defined by this specification,
new values are added to the registry by Expert Review with
Specification Required, using the Designated Expert process
defined in RFC 5226 [3].
This section provides guidance to designated experts so that
they may make decisions using a philosophy appropriate for these
registries.
[snip]
All values in these IANA registries MUST be
documented in a specification that is clear, permanently and
publicly available, and likely to ensure interoperability. IETF
standard values MUST be useful and not harmful to the Internet.
Designated experts should encourage vendors to avoid defining
similar but incompatible values and instead agree on a single
IETF standard value. However, it is beneficial to document
existing practice.
I will let Alexey make the full case for removing the requirement
for expert review of vendor-specific values. I think that the main
thrust of the argument is that we should encourage vendors to
document the values that they use.
