四分律行事鈔資持記 3.1112

3.1112

題標諸部，通指外宗；若據篇中，亦引《四分》，乃是對顯本異不同。別行二釋，亦同前解。

The title denotes 'the various schools', broadly referring to external traditions; if based on what is in the chapter, it also cites the Dharmaguptaka-vinaya, which serves to contrast and clarify the differences between the root tradition and others. The separate explanation in two commentaries also follows the previous interpretation.
