大般涅槃經義記 9.263

9.263

通行七者，一一人中皆通三乘。今此偏就通行論七，但下文中初二後一彰通隱別，中間四人偏舉小乘略不論大。

As for the seven of common practice, within each and every person [the stages] are common to the three vehicles. Here, we specifically discuss the seven with reference to common practice, yet in the text below, the first two and the last one manifest the common while concealing the separate, whereas the middle four persons specifically adduce the Hīnayāna and omit discussing the Mahāyāna.
