Internet-Draft Road and House Prefix January 2010
1. Terminology
This document uses terminology described in [RFC4119].
1.1. Introduction
RFC4119 updated by RFC5139 defines suffixes for street names and
house numbers, but does not define prefixes. Both occur regularly in
addresses and CAtypes are needed for them. This memo defines STP
Street Prefix and HNP house number prefix CAtypes.
1.2. Prefixes in addressing
In [RFC4119] one can define a PIDF for 123 Main Street but not 123
Boulevard Coranado. There is an STS CAtype for a suffix, but no
corresponding prefix. [RFC5139] added PRM Premodifier and POM
Postmodifier, but those are not suitable for the purpose.
Similarly, one can express 123B Main, but not H123 Main. Although
one can include such letters in the house number, most addressing
authorities keep the number numeric only to facilitate sorting, and
have prefix and suffix fields for alphanumerics that appear in front
of or following the numeric house number.
To remedy this situation, new CAtypes are required: STP for a street
(road) prefix, and HNP for a house number prefix.
1.3. Security Considerations
The XML representation described in this document is designed for
inclusion in a PIDF-LO document. As such, it is subject to the same
security considerations as are described in [RFC4119].
Considerations relating to the inclusion of this representation in
other XML documents are outside the scope of this document.
1.4. IANA Considerations
This document updates the civic address type registry established by
[RFC4776]. Two additional value are added:
41 STP Street (Road) Prefix
42 HNP House Number Prefix
