The Convention does not cover domestic flights. Indeed, under section 2 of Danish Air Navigation Act foreign registered aircraft may not make a domestic flight within Denmark unless there is a agreement with the State of Registry which permits such flights or permission of the Minister of Transport is obtained.

Which part precisely do you mean? Paragraph 2 in Chapter 1? I don't think you can construe "aviation within Danish territory" to apply only to domestic flights. The Chicago Convention would seem to be the focus of 2(b), that requires an "agreement with the state of registry".
All in all, it doesn't look substantially different from Art 3 of the UK's ANO.
I also think you go too far in suggesting that the Chicago Convention does not apply to domestic flights. It does where the stops are for non-traffic purposes. I don't believe the phrasing used was intended to prevent other than cabotage -- i.e. remunerated domestic flights. You need to read it in the context of the remainder of Art 5 and Art 7.
