I don't think there is any documentation for this. There are however various posts by @DaveBlake that cover some of this.
With regard to recentlyaddedalbums, there is no filtering applied when using the db path so your genre rule is just ignored. As @LongMan points out, you can achieve a similar thing through smartplaylists (which you can then convert into nodes if you wish) although using the 'dateadded' field may return different albums to the recentlyaddedalbums node as that doesn't use the date to create it's list.
If you want to dig through the code to see what options you can use for filtering, you can look at https://github.com/xbmc/xbmc/blob/master...383-L11963
