Mauro,
targetAttributeNode must be applied to the containing property type
lcv:landCoverObservation[1]/lcv:LandCoverObservation, not the terminal
node. I am not sure exactly what you should use in this case, but please
see these pages for examples:
http://docs.geoserver.org/latest/en/user/data/app-schema/mapping-file.html#targetattributenode-optional
http://docs.geoserver.org/latest/en/user/data/app-schema/polymorphism.html#any-type
Kind regards,
Ben.
