 		<meta property="se:production-notes">Removed xml:lang="ru-Latn" tag from ‘nihiline’ in chapter-6-208. ‘Нигилизм’ is ‘nihilism’ in Russian, but 'нигилин' is not a Russian word, as it would need to be for this tag to be appropriate. ‘Nihilin’ is Nietzsche’s German and it’s another coinage of his, a play on Latin nihil + German Anilin (English aniline), glossed as ‘a poisonous chemical’ in the newest OWC edition. In an English translation, then, ‘nihiline’ is just a neologism, not a transliteration, so should be just `i` in accordance with 8.2.10.1</meta>
