[gdal-dev] WFS-T Transaction serializes Date/DateTime fields in non-ISO format

Hi,

I've found that GDAL 3.12.1 serializes Date and DateTime fields incorrectly
in WFS-T Transaction requests — using / as date separators and a space
instead of T between date and time components. This is not compliant with
W3C XML Schema Part 2, which defines the formats required by OGC WFS:
YYYY-MM-DD and YYYY-MM-DDTHH:MM:SSZ.

A similar issue was previously fixed in the GML driver:
https://github.com/OSGeo/gdal/issues/2897 - should the same fix be applied
to the WFS-T writer?
