The DTG is incorrect or not correctly converted

DTG: 20161108/0100Z

In XML should be:

<iwxxm:issueTime>
   <gml:TimeInstant gml:id="uuid....">
      <gml:timePosition>2016-11-08T01:00:00Z</gml:timePosition>
   </gml:TimeInstant>
</iwxxm:issueTime>

Or fix in the TAC of course (my choice, case where DTG and first observation are different)

DTG: 20161108/0000Z

There is not replaced advisory number and the advisory number is incorect

So the xml is wrong.

First the tag iwxxm:replacedAdvisoryNumber must have NOT be present Second: the value of tag iwxxm:advisoryNumber is incorrect:

<iwxxm:advisoryNumber>2016/2</iwxxm:advisoryNumber> should be <iwxxm:advisoryNumber>2016/1</iwxxm:advisoryNumber>

@blchoy Is this addressed in the 2025-2 RC?

[blchoy]

My understanding is that this example no longer exists in Amendment 82; and all examples have also been moved from Annex 3 to PANS-MET. We have yet to see the consolidated PANS-MET to confirm.

But regarding the mentioned example in IWXXM 2023-1 there will be no applicable workflow to update, isn't it?
