金剛經纂要刊定記 1.89

1.89

配入名相者。謂有疏將法相名句配入其中，此則貪著其事，好尚法相也。如下經云：「凡夫之人貪著其事。」乖宗者，以經宗無相真空，既以法相解之，寧契經旨，以不順理名之為乖。

As for "matching with technical terms (dharmalakṣaṇa)": this means there is a commentary that forces the names and phrases of the Dharma's characteristics into it. This is being greedily attached to external affairs and having a fondness for dharmalakṣaṇa. As the sūtra below states, "Ordinary persons are greedily attached to these things." "Departing from the central tenet" is because the sūtra's tenet is markless true emptiness; since one explains it through dharmalakṣaṇa, how could it tally with the sūtra's intent? Failing to conform to principle is termed "departing from."
