This document changes the policy of the "Location-to-Service Translation (LoST) Location Profiles" IANA registry established by RFC 5222 from Standards Action to Specification Required. This allows standards development organizations (SDOs) other than the IETF to add new values.

The Location-to-Service Translation (LoST) Protocol [RFC 5222] uses a location profile when conveying location (e.g., in a mapping request and a service boundary result). [RFC 5222] established an IANA registry of location profiles [reg] with a registry policy of Standards Action. This requires a Standards Track RFC for any new registry values. The National Emergency Number Association (NENA) is a standards development organization (SDO) that makes significant use of LoST in its emergency call specifications (e.g., [NENA-i3]) and has identified a need for additional location profiles. This document changes the registry policy to Specification Required, allowing other SDOs such as NENA to add values.

This document changes the policy of the "Location-to-Service Translation (LoST) Location Profiles" IANA registry [reg] established by [RFC 5222] from Standards Action to Specification Required (as defined in [RFC 8126]). This allows SDOs other than the IETF to add new values.

No new security considerations are identified by this change in registry policy.

IANA has changed the policy of the "Location-to-Service Translation (LoST) Location Profiles" registry (established by [RFC 5222]) to Specification Required. IANA has also added this document as a reference for the registry. The Expert Reviewer is designated per [RFC 8126]. The reviewer should verify that:

• the proposed new value is specified by the IETF, NENA, or a similar SDO in which location profiles are in scope;
• the proposed new value has a clear need (which includes there not being an existing profile that meets the need); and
• the profile specification is unambiguous and interoperable.

Many thanks to Ted Hardie for his helpful review and suggestions and to Guy Caron for his suggestion to clarify that "clear need" includes there not being an existing profile.
