          The LoST-Validation S-NAPTR Application Service Tag
                    draft-gellens-lost-validation-09

Abstract

   This document adds the "LoST-Validation" service tag to the
   Straightforward Naming Authority PoinTeR (S-NAPTR) Application
   Service Tag IANA registry.  This tag can appear in a Naming Authority
   Pointer (NAPTR) Domain Name System (DNS) record to assist clients of
   the Location-to-Service Translation Protocol (LoST) in identifying
   LoST servers explicitly willing to perform location validation.  This
   tag and the information on its use is an update to RFC5222 that
   enables the explicit discovery of a server that supports location
   validation.

1.  Document Scope

   This document adds 'LoST-Validation' to the S-NAPTR Application
   Service Tag IANA registry, and describes how this tag fits in the
   LoST server discovery procedure described in [RFC5222].  This tag is
   used with Naming Authority Pointer (NAPTR) Domain Name System (DNS)
   records so that clients of the Location-to-Service Translation
   Protocol (LoST) [RFC5222] can identify servers explicitly willing to
   perform location validation.  This tag and the information on its use
   is an update to [RFC5222] that enables the explicit discovery of a
   server that supports location validation.

2.  Introduction

   The Location-to-Service Translation Protocol, LoST [RFC5222] defines
   a mapping service with the additional ability for a client to request
