While in the edicts of other emperors, there is a phrase that means 'to take the faculty of Imperial Sun Succession (Amatsuhitsugi) to the Imperial Throne (Takamikura) according the law that Emperor Tenchi established for the first time,' in the edict of KoKo this phrase is substituted by another phrase that says 'the faculty of Imperial Sun Succession (Amatsuhitsugi) to the Imperial Throne (Takamikura) is 'the law that Emperor Tenchi established for the first time.'
他の天皇で「天日嗣高座の業を天智天皇が初め定めた法に従って受けよ」」という意味になるところが、光孝では「天日嗣高座の業は天智天皇が初め定めた法である」と変わっている。
