Palumbo discusses this text in some detail. It comprises "an almost complete prātimokṣa text, the earliest known in China and with no transmitted counterpart. It was copied under the W. Liang 西涼, ruling in Gansu...and bears a colophon written on 10 January 406...which makes it the oldest dated item from the cave library". Palumbo also cites previous studies by Yabuki and Tsukamoto. There is significant overlap between the final part of the text and EĀ 48.2 (a composite text).
