I don't believe it is. I know "way back" (on PC) they lowered the max enchant level from 50 to 30, so this version is limited to 30 due to the version it is based upon. Does that answer your question properly?
Tought that too! I remembered in pc i made 31 or 32 level enchantments or something and i tried on PS3 do all the tricks with even sticky pistons to make library sealed with bookshelves as you enter it. Im okay with 30, easy and fast!
Haha yup just get a small xp spawner going and you should be good to go
