The TSMG has approved this code system as an exemption from moving to THO on 7th May 2026. This code system is appropriately defined in the FHIRPath specification as it is similar to a required code binding in FHIR. https://confluence.hl7.org/spaces/TSMG/pages/453915259/2026-05-07+TSMG+Agenda+and+Minutes

INFORMATION: CodeSystem/calendar-units: CodeSystem: Most code systems defined in HL7 IGs will need to move to THO later during the process. Consider giving this code system a THO URL now (See https://confluence.hl7.org/display/TSMG/Terminology+Play+Book, and/or talk to TSMG) (1 uses)

This specification pre-dates the conformance clause marking functionality, it may be added in a future publication

INFORMATION: en/index.html: The html source contains the word 'SHALL' but it is not in a text phrase marked as a conformance clause: 'This specification uses the conformance verbs SHALL, MUST, SHOULD, and MAY as defined in RFC 2119. Unlike RFC 2119, however, this specification allows that different applications might not be able to interoperate because of how they use optional features. In particular:' (1 uses)
