Hi, Tuesday (10 August 1999)

Three corrections (with rationales below):

1) Please add an 'Internationalization Considerations' section,
as required by RFC 2277 (see below);
2) Please change the default charset of 'InternationalDisplayString'
from 'NVT-ASCII' back to 'UTF-8' (transform of ISO 10646/Unicode);
3) Please change the datatype of 'hrNetworkIfIndex' in 'hrNetworkTable'
from 'InterfaceIndexOrZero' back to 'INTEGER'.

Rationale 1
-----------

The missing 'Internationalization Considerations' section is REQUIRED
for all Internet 'standards track' documents, in order to be:

a) Compliant with the "IETF Policy on Character Sets and Languages",
RFC 2277 / BCP 18, January 1998
- section 6 'Documenting internationalization decisions';
b) Compliant with the "Guide for Internet Standards Writers",
RFC 2360 / BCP 22, June 1998
- section 2.17 'Internationalization'.

Rationale 2
-----------

In Bobby Krupczak's previous draft, the default character set of the
datatype 'InternationalDisplayString' was clarified to be 'UTF-8'. That
change has been replaced by a default of 'NVT-ASCII' in the current
draft. The clarified 'InternationalDisplayString' default of 'UTF-8'
is required, in order to be:

a) Compliant with the "IETF Policy on Character Sets and Languages",
RFC 2277 / BCP 18, January 1998
- which requires that all protocols that convey human-readable text
default to 'UTF-8' (transform of ISO-10646);
b) Consistent with the Draft Standard SNMPv3 specifications and MIBs,
RFC 2571-2575, April 1999
- which use 'SnmpAdminString' (fixed charset of 'UTF-8') exclusively
and do NOT use 'DisplayString' anywhere;
c) Consistent with the Proposed Standard "Internationalization of FTP",
RFC 2640, July 1999
- which requires that all conformant FTP implementations use default
charset of 'UTF-8' for text parameters.

Specifically, the HR MIB object 'hrSystemInitialLoadParameters' of type
'InternationalDisplayString' CANNOT interwork with RFC 2640 compliant
FTP implementations, unless the default charset is 'UTF-8'.

Rationale 3
-----------

The change of 'hrNetworkIfIndex' to datatype 'InterfaceIndexOrZero'
(imported from the "Interfaces Groups MIB using SMIv2", RFC 2233)
creates a dependency on a 'Proposed Standard' (RFC 2233) which would
automatically block the HR MIB from advancing to 'Draft Standard'.

Please correct these errors before forwarding this draft to the IESG.

Thanks,
