[Geopriv] [geopriv] #35: IANA Considerations

#35: IANA Considerations

---------------------------------------+------------------------------------
In -09, material relating to IANA considerations is included in sections
other than IANA Considerations section. In order to make it more likely
that IANA will correctly interpret the guidance, it is advisable to
consolidate guidance relating to parameter allocation into the IANA
Considerations section.

Proposed text:

4. IANA Considerations

IANA has assigned a DHCPv4 option code of 123 for the GeoConf option
defined in this document. Assignment of a DHCPv6 option code is
requested.

The GeoConf Option defines two fields for which IANA maintains a
registry: The Altitude Type (AT) field and the Datum field (see
Section 2). The datum indicator MUST include specification of both
horizontal and vertical datum. New values for the Altitude Type (AT)
and Datum fields are assigned through "Standards Action" [RFC5226].
New Altitude Types and datums MUST define the way that the 30 bit
value and the associated 6 bit uncertainty are interpreted. The
initial values of the Altitude registry are as follows:

AT = 1 meters of altitude defined by the vertical datum specified.

AT = 2 building floors of altitude.

Datum = 1 denotes the vertical datum WGS 84 as defined by the EPSG as
their CRS Code 4327; CRS Code 4327 also specifies WGS 84 as
the vertical datum

Datum = 2 denotes the vertical datum NAD83 as defined by the EPSG as
their CRS Code 4269; North American Vertical Datum of 1988
(NAVD88) is the associated vertical datum for NAD83

Datum = 3 denotes the vertical datum NAD83 as defined by the EPSG as
their CRS Code 4269; Mean Lower Low Water (MLLW) is the
associated vertical datum for NAD83

This document defines the Ver field for the DHCPv4 and DHCPv6
options. New values for the Ver field are assigned through
"Standards Action" [RFC5226]. Initial values are as follows:

0: DHCPv4 Implementations conforming to [RFC3825]
1: Implementations of this specification (for both DHCPv4 and DHCPv6)
