Williams argues that the Upali-paripr̥cchā T325 was most likely translated by *Dharmakṣema, not Dharmarakṣa. His grounds are as follows: Sengyou states in CSZJJ that the text was translated in the Liangzhou region under the Jin. The translation uses the term chanhui 懺悔, not huiguo 悔過, which Williams regards as having probably been coined around 400 CE.
