      • See notes in issue #321
      • Seems that the small team settled for TT=WM (TAC) and LM (IWXXM). Will confirm at upcoming WG-MIE telecon on 15 Jul.
    • Choy to provide a fix to the schematron for 3.0 and post it along with the issue discussions.
  4. Outcome of MIE/10 (Choy)
    • WMO Abbreviated Headers - As the proposal to retire WMO No.386 will only be raised in INFCOM-3 in mid-2024, it is still possible handle the request to introduce new headers for VONA and QVA. After that, the headers will be moved into a standalone document to be maintained only for aviation purposes at the request of ICAO.
    • Communication of IWXXM releases:
      • Workflow, distribution means and target recipients to be confirmed.
      • Recommend METP to inform all working groups to take into account the time needed for stakeholders to implement IWXXM changes (which could be 12-18 months after the publication of the schemas) in determining the applicable date of the associated SARPs.
    • IWXXM extension:
      • Global extension repository - MIE will continue to expedite implementation of the repository by ICAO.
      • Raising State extensions to IWXXM core - Further discussion is required.
      • Notification of changes to IWXXM core and extensions - Further discussion is required.
    • New IWXXM design - A trimmed down version of IWXXM, know as IWXXM-SX, is made available for experimental development work on new information services like aerodrome observation and forecast, as well as HWIS.
    • Retirement of IWXXM collective bulletin - Further discussion is required on the need to aggregate reports as well as the use of the WMO COLLECT construct to encapsulate reports for transmission.
    • Removal of TAC from ICAO Annex 3 - The plan is to remove TAC as a Standard in Amendment 83 (Nov 2029).
