In the Taishō, T1422 is presented in two versions. This version, T1422a, bears a footnote (T1422 [XXII] 196 n. 16) stating, "This Vinaya varies greatly between the four editions, viz. Song, Yuan, Ming and 'Palace'. Here, we present the Song edition, noting variants in the Yuan and 'Palace' editions" 此律與宋元明宮四本大異今以宋本元本宮本對校.
