I would add that there is a sentence in paq'batlh:

DaH naDev jIHtaHbogh meq Saja'

(interestingly, in {qamchIyDaq 'uQ'a'})

Before the qep'a', I suggested (apparently, on FB) that Maltz comments on the grammar of this sentence; hopefully, more light will be shed at the upcoming qepHom'a'.

I am also quite interested in which nouns can serve as head nouns of a {-bogh} clause when the clause relates to its own entirety rather than to its subject or object (poH? ngoD/ghu'? Daq? nger/qech?).
