大方廣佛華嚴經隨疏演義鈔 14.18

14.18

疏「六諸法但名宗」者，則顯出世亦假名耳。故云一切我法亦如《中論》，若有世間則有出世間，既無世間何有出世間等。

Regarding the commentary's phrase "Sixth, the tenet that all phenomena are merely nominal": this reveals that the supramundane is also merely nominal. Hence it says that all selves and phenomena are also like the Madhyamakaśāstra: if there is a mundane, there is a supramundane; since there is no mundane, how could there be a supramundane, and so on.
