金剛般若波羅蜜經註解 1.171

1.171

解譯無此一句。無實、無虛者，如來所證之法本離言說，故曰無實；對機有說，故曰無虛也。

The translated commentary lacks this sentence. "Neither real nor void": the dharma realized by the Tathāgata is fundamentally separate from spoken discourse, hence it says "not real"; yet in response to capacities there is teaching, hence it says "not void."
