The condition for qualification was dependent on a fact of SubLink type annotation. But initially columns are qualified depending on existence of an external input. Actually it seems that the existence of an external input is a right condition for column qualification. commit_hash:d03011a0f70ee94bf05418326cd4b6c655c5999f
