I'll add that no mention is made of David or Davidic messianism. Not all sects of Judaism shared that particular idea and it would appear the author had opportunity but did not include this concept.
It’s impossible to say for sure. The book of Daniel overall is intentionally cryptic. Davidic lineage was obviously a prominent belief, and the author of Daniel doesn’t specify any other lineage, though it’s possible that the author had some alternative in mind (and likely favouring the Maccabees). One ‘benefit’ of being less specific is it allows greater latitude for supposed ‘fulfilments’, which may or may not have also been intentional.
