[tlhIngan Hol] Is Daq'a' canon ?

A little bird told me, that in a deleted scene of the 2009 star trek movie, appears the phrase: tlhIngan wo' Daq'a' bo'elpu' you have entered the jurisdiction of the klingon empire Does anyone know, whether this phrase was written by 'oqranD ? Is the above translation of {Daq'a'} = jurisdiction, canon ? ~ nI'ghma
