Hi Lorenzo, XSD modules can be pretty asymmetric, some can parse but not encode, others do both but with significantly different success rate.
I believe gt-xsd-kml might be of the latter type... nothing else is using it in GeoTools, in GeoServer the only supported module using it is the importer, which only uses the read (parse) side of it. There is also an unsupported kmlppio module that can encode KML, but... I believe it has not received usage in ages. Long story short... fixes welcomed.
