A LoST extension to return complete and similar location info
draft-ietf-ecrit-similar-location-08
Abstract
This document introduces a new way to provide returned location
information in LoST responses that is either of a completed or
similar form to the original input civic location, based on whether
valid or invalid civic address elements are returned within the
findServiceResponse message. This document defines a new extension
to the findServiceResponse message within the LoST protocol [RFC5222]
that enables the LoST protocol to return a completed civic address
element set for a valid location response, and one or more suggested
sets of similar location information for invalid LoST responses.
These two types of civic addresses are referred to as either
"complete location" or "similar location", and are included as a
compilation of CAtype xml elements within the existing LoST
findServiceResponse message structure.

1. Introduction
The LoST protcol [RFC5222] supports the validation of civic location
information as input, by providing a set of validation result status
indicators. The current usefulness of the supported xml elements,
"valid", "invalid", and "unchecked", is limited, because while they
each provide an indication of validity for any one location element
as a part of the whole civic address, the mechanism is insufficient
in providing either the complete set of civic address elements that
the LoST server contains, or of providing alternate suggestions
(hints) as to which civic address is intended for use.
Whether the input civic location is valid and missing information, or
invalid due to missing or wrong information during input, this
document provides a mechanism to return a complete set of civic
address elements for those valid or invalid cases.
