As I said, the databook (apparently) doesn't include the natures one can have through Tailed Beasts. Only "Wind Release" is marked in Naruto's elemental circle. I don't know the difference between a marked Yin&Yang and an unmarked, so I can't say more about that. But the page about YYR Techniques states that Naruto really has YYR (I could be wrong about this, though. The wording is weird to me).

To know more about this, we'd need Danzo's page. He should be listed as a Kekkei Genkai user, since he actually has the special DNA. It could also be the case the the Tailed Beast's Kekkei Genkai aren't really Kekkei Genkai, although I think that to be unlikely.

In the end, it's as always better to wait for the full book. We have a preview and we have some information, but for bigger things, we should wait.
