Source: gdal
Version: 3.2.2+dfsg-2
Severity: important
Tags: upstream
Control: fixed -1 gdal/3.3.3+dfsg-2
Control: fixed -1 gdal/3.4.0~rc1+dfsg-1~exp1

Dear Maintainer,

The LVBAG driver introduced in GDAL 3.2.0 is buggy and doesn't (fully)
support BAG 2.0 Extract files [0].

In GDAL 3.3.0 significantly improves support for the XML schema of
BAG 2.0 Extract files [1][2][3][4][5][7][8], but this is still not complete.

GDAL 3.3.0 also contains cppcheck fixes for the driver [6].

In GDAL 3.4.0 two changes were added [9][10] which complete support for the
BAG 2.0 Extract XML schema.

These changes from 3.3.0 & 3.4.0 need to be added to the package in bullseye
to fix the processing of BAG 2.0 Extract files for stable users.
