Non-CityGML content is skipped

Hi there,

i am struggling when converting citygml files to cityjson, when there are non-CityGML namespacesused. is it basically not possible to convert this file? gml.txt

[15:57:33 INFO] Starting citygml-tools.
[15:57:33 INFO] Executing 'to-cityjson' command.
[15:57:33 INFO] Found 1 file(s) at gml.gml.
[15:57:34 INFO] [1|1] Processing file /mnt/c/Users/Johannes/Desktop/gml.gml.
[15:57:34 WARN] The input file uses unsupported non-CityGML namespace(s): http://repository.gdi-de.org/schemas/adv/produkt/alkis-vereinfacht/2.0, http://www.opengis.net/wfs.
[15:57:34 INFO] Non-CityGML content is skipped unless a matching ADE extension has been loaded.

[15:57:34 INFO] citygml-tools finished with 1 warning(s).

or whats the trick behind it? what is meant with "ADE extension has been loaded"? or: how does such a ADE extension look like or what is that?

Cheers and thanks

this would be an alternative file with the same result: generated from here
