Correct STNR movement documentation for SIGMET and AIRMET #313

Closed jkorosi closed 1 year ago

jkorosi commented 1 year ago

We need to distinguish between cases when

  1. movement is stationary
  2. movement is not reported at all. That means even the forecast at the end of the validity ( element) is not reported. This case can occur when VA or TC SIGMET is created from advisory where only the +6h forecast affects the FIR, so no movement information is available.

The TAC-to-XML-Guidance.txt STNR for SIGMET and AIRMET description is correct. Therefore I also used it in the related XSD schemas documentation.

This issue is related to issue #282.
