[tlhIngan Hol] [The Little Prince] Is {DI'raq} "sheep" new canon?

As I checked the Klingon Wiki updates today, I came across {DI'raq loD} as an example of a noun-noun construction as opposed to a compound noun http://www.klingonwiki.net/En/CompoundNoun The source was The Little Prince, and on its wiki page http://www.klingonwiki.net/En/TheLittlePrince it is stated that "Marc Okrand has provided several new words for the creation of this translation." The latter wiki page includes another example of {DI'raq}, though I presume that _sentences_ in {ta' puq mach} are non-canon, just like Star Trek: Discovery. Lieven, could you comment on the status of {DI'raq}? Is there anything you could reveal before the book is published? Qapla'!
