ICAO Annex 3 Amendment 79/80
With IWXXM 2021-2 Release:
- Tropical Cyclone Advisory schema now has the 'intensityChange' element. The TCA XML Encoder includes it now;
- Missing forecast position and/or maximum wind speed in TCA better handled in the schema;
- Most nilled elements now require explicit utilization of the
xsi:nil
attribute; - TAF Encoder now processes <12hr TAFs -- recognition of T1T2 == 'TC' as a TAF code form.
